LHC to run at 3.5 TeV for early part of 2009-2010 run rising later
Link

Geneva, 6 August 2009

CERN'sLarge Hadron Collider will initially run at an energy of 3.5 TeV per beam when it starts up in November this year. This news comes after all tests on the machine's high-current electrical connections were completed last week, indicating that no further repairs are necessary for safe running.

"We've selected 3.5 TeV to start," said CERN's Director General, Rolf Heuer, "because it allows the LHC operators to gain experience of running the machine safely while opening up a new discovery region for the experiments."

Following the incident of 19 September 2008 that brought the LHC to a standstill, testing has focused on the 10,000 high-current superconducting electrical connections like the one that led to the fault. These consist of two parts: the superconductor itself, and a copper stabilizer that carries the current in case the superconductor warms up and stops superconducting, a so-called quench. In their normal superconducting state, there is negligible electrical resistance across these connections, but in a small number of cases abnormally high resistances have been found in the superconductor. These have been repaired. However, there remain a number of cases where the resistance in the copper stabilizer connections is higher than it should be for running at full energy.

The latest tests looked at the resistance of the copper stabilizer. Many copper connections showing anomalously high resistance have been repaired already, and the tests on the final two sectors, which concluded last week, have revealed no more outliers. This means that no more repairs are necessary for safe running this year and next.

"The LHC is a much better understood machine than it was a year ago," said Heuer. "We can look forward with confidence and excitement to a good run through the winter and into next year."

The procedure for the 2009 start-up will be to inject and capture beams in each direction, take collision data for a few shifts at the injection energy, and then commission the ramp to higher energy. The first high-energy data should be collected a few weeks after the first beam of 2009 is injected. The LHC will run at 3.5 TeV per beam until a significant data sample has been collected and the operations team has gained experience in running the machine. Thereafter, with the benefit of that experience, the energy will be taken towards 5 TeV per beam. At the end of 2010, the LHC will be run with lead ions for the first time. After that, the LHC will shut down and work will begin on moving the machine towards 7 TeV per beam.

Problems with the LHC... Large Hadron Collider

LHC re-start scheduled for 2009

Geneva, 23 September 2008. Investigations at CERN1 following a large helium leak into sector 3-4 of the Large Hadron Collider (LHC) tunnel have indicated that the most likely cause of the incident was a faulty electrical connection between two of the accelerator’s magnets. Before a full understanding of the incident can be established, however, the sector has to be brought to room temperature and the magnets involved opened up for inspection. This will take three to four weeks. Full details of this investigation will be made available once it is complete.

“Coming immediately after the very successful start of LHC operation on 10 September, this is undoubtedly a psychological blow,” said CERN Director General Robert Aymar. “Nevertheless, the success of the LHC’s first operation with beam is testimony to years of painstaking preparation and the skill of the teams involved in building and running CERN’s accelerator complex. I have no doubt that we will overcome this setback with the same degree of rigour and application.”

The time necessary for the investigation and repairs precludes a restart before CERN’s obligatory winter maintenance period, bringing the date for restart of the accelerator complex to early spring 2009. LHC beams will then follow.

Particle accelerators such as the LHC are unique machines, built at the cutting edge of technology. Each is its own prototype, and teething troubles at the start-up phase are therefore always possible.

“The LHC is a very complex instrument, huge in scale and pushing technological limits in many areas,” said Peter Limon, who worked on commissioning the world’s first large-scale superconducting accelerator, the Tevatron at Fermilab in the USA. “Events occur from time to time that temporarily stop operations, for shorter or longer periods, especially during the early phases.”

CERN has received similar words of support from several laboratories, including Germany’s DESY, home of the HERA superconducting particle accelerator, which ran from 1992 to 2007.

"We at DESY have been following the commissioning of the LHC with great excitement and have been very impressed with the success of the first day,” said Albrecht Wagner, DESY Director. “I am confident that our colleagues at CERN will solve the problem speedily and we will continue to support them as much as we can."

LHC Kritics in Switzerland, Germany and Austria survived the first ruling on their case by the European Court for Human Rights, August 29th. So did CERN's Large Hadron Collider, which will go ahead while the court action continues. A stunningly quick decision by the ECHR only 3 days after the complaint was filed against CERN and its 20 member countries from the EC denies any Interim Measures that would have forced CERN to suspend operations of the LHC.

Soon to be the world's most powerful atom smasher and the biggest and most costly science experiment ever, the $10 billion LHC straddles the borders of Switzerland and France, near Geneva. CERN, the giant European nuclear physics lab, has completed the 17 mile underground construction of the ring accelerator and is now in the first stages of start-up. It's goal is to unlock the secrets of the early Universe, through unparalled high energy collisions of hadrons, protons at first and then heavy lead ions. Critics believe that the LHC could pose enormous dangers to the planet.

Markus Goritschnig, a spokesman for LHC Kritics said, "This quick decision of the court to dismiss the claim for Interim Measures is not a negative sign as such. The Court is studying the whole appeal in detail now. Only the claim for Interim Measures was rejected, not the appeal itself." The Court gave no reasons for dismissing the preliminary injuction to stop LHC operations.

"The case before the European Court of Human Rights," said Dr James Gillies, chief spokesman for CERN, commenting on the Court case in the Telegraph, "contains the same arguments that we have seen before and we have answered these in extensive safety reports."

All 12 points in the LHC Kritics arguments are being considered by the ECHR. Other safety hazards have been studied in the latest CERN LHC Safety Assessment Group report, including theoretical objects and dangers that might be produced at the LHC like micro black holes. MBH is the main focus in the Court suit. CERN concludes there is no risk.

LHC Kritis strongly disagree on the level of risk and CERN's claim that they have addressed it. "In the complaint", said Markus Goritschinig, "we took all the safety arguments into consideration that were given by CERN in their standard reactions to the global risk. They will have to produce a better LSAG report."

There are three principal signatories to the suit, one each from Switzerland, Germany and Austria. In the suit Dr. Otto E. Rössler's theories on mBH figure prominently, though he is not involved with the court challenge. In answer to Dr James Gillies, he told me that CERN still has not disproved his general relativistic theory on mBH or proved that neutron stars are immune to mBH because mBH don't exist. Dr Rössler said these, the most dense stars, are not attacked by mBH because they are protected by their own superfluidity, so mBH pass through them as there is no friction. MBH can exist in space, he insists. Dr Rössler said, "This unproven argument does not impart any security onto earth as CERN alleges."

Dr Rössler added that there is further confirmation of his theory that mBH do not evaporate, contrary to what Professor Stephen Hawking states, through his Hawking radiation theory. "I just learned about an earlier proof of non-evaporation given by Vladimir Belinski, Institute des Hautes Etudes Scientifiques at Bures-sur-Yvette, France, in Physics Letters A. (Vol 209, p 13)

The authors of the Euro suit have included a new study on the mBH question, not considered in the LSAG report as both are recent documents. The paper by Dr Rainer Plaga, a German physicist, that supports Dr Rössler on possible mBH production and dangers, uses quantum physics arguments as CERN does. Markus Goritschnig thinks that Dr Plaga's work is an compelling contribution to the argument for dangerous mBH. "Plaga says the first consequence of producing black holes in lower dimensions would be a disastrous explosion. Then the semi-stable black hole would intensively radiate, consuming 17,000T of material each year. It would be unremovable, undestroyable, and surely endanger the planet as a whole."

Dr Rössler is due to meet with the Swiss President, Pascal Couchepin, this fall on LHC safety issues. According to a spokeswoman for the ECHR, "The proceedings before the Strasbourg Court are expected to take several years."

CERN management confirms new LHC restart schedule
Link

Geneva, 9 February 2009. CERN1 management today confirmed the restart schedule for the Large Hadron Collider (LHC) resulting from the recommendations from last week’s Chamonix workshop. The new schedule foresees first beams in the LHC at the end of September this year, with collisions following in late October. A short technical stop has also been foreseen over the Christmas period. The LHC will then run through to autumn next year, ensuring that the experiments have adequate data to carry out their first new physics analyses and have results to announce in 2010. The new schedule also permits the possible collisions of lead ions in 2010.

In Chamonix there was consensus among all the technical specialists that the new schedule is tight but realistic.

“The schedule we have now is without a doubt the best for the LHC and for the physicists waiting for data,” said CERN Director General Rolf Heuer. “It is cautious, ensuring that all the necessary work is done on the LHC before we start up, yet it allows physics research to begin this year.”

This new schedule represents a delay of six weeks with respect to the previous schedule, which foresaw the LHC “cold at the beginning of July”. The cause of this delay is due to several factors such as implementation of a new enhanced protection system for the busbar and magnet splices; installation of new pressure-relief valves to reduce the collateral damage in case of a repeat incident; application of more stringent safety constraints; and scheduling constraints associated with helium transfer and storage.

The enhanced protection system measures the electrical resistance in the cable joints (splices) and is much more sensitive than the system existing on 19 September.

The new pressure relief system has been designed in two phases. The first phase involves installation of relief valves on existing vacuum ports in the whole ring. Calculations have shown that in an incident similar to that of 19 September, the collateral damage would be minor with this first phase. The second phase involves adding additional relief valves on all the dipole magnets and would guarantee minor collateral damage (to the interconnects and super-insulation) in all worst cases over the life of the LHC.

The management has decided for 2009 to install the additional relief valves on four of the LHC’s eight sectors, at the same time as repairs in the sector damaged last September and other consolidation work already foreseen. The dipoles in the remaining four sectors will be equipped in 2010. 1. CERN, the European Organization for Nuclear Research, is the world's leading laboratory for particle physics.

Russia threatens to supply Iran with top new missile system as 'cold war' escalates
Link
Russia is deploying the threat to sell a "game changing" air defence system to Iran as a high stakes bargaining chip in its new "cold war" with America, The Sunday Telegraph has learned.
By Philip Sherwell in New York and William Lowther in Washington
Last Updated: 11:29AM BST 31 Aug 2008

US intelligence fears the Kremlin will supply the sophisticated S-300 system to Tehran if Washington pushes through Nato membership for its pro-Western neighbours Georgia and Ukraine.

The proposed deal is causing huge alarm in the US and Israel as the S-300 can track 100 targets at once and fire on planes up to 75 miles away.

That would make it a "game-changer", greatly improving Iranian defences against any air strike on its nuclear sites, according to Pentagon adviser Dan Goure. "This is a system that scares every Western air force," he said.

Senior US intelligence operatives believe that Russia is planning to use a stand-off over the S-300 to create a foreign policy showdown that would test the mettle of a new US president.

Republican candidate John McCain has taken a strongly anti-Kremlin line on a series of international issues and backed Georgia's desire to join Nato. His Democratic rival Barack Obama has also indicated he supports Nato membership for Georgia.

"The message from Moscow is very clear," said George Friedman, director of Stratfor, a leading US private intelligence agency. "They are saying if you don't stop meddling in our sphere of influence, this is what we are going to do.

"Back Georgia and Ukraine for Nato membership and you'll see the S-300 to Iran. It is a very powerful bargaining chip and a major deterrent to US actions in the region. Moscow is playing very strategically on America's obsession with Iran."

Moscow has been infuriated by the steady encroachment of Nato into the former Soviet bloc and the recent granting of independence to the ex-Serbian province of Kosovo against its wishes.

After American condemnation of Russia's foray into Georgia, Moscow invited Syria's dictator Bashar al-Assad, a long-time US foe, to discuss military deals in a deliberate signal of how it could cause trouble for Washington.

A senior US intelligence operative who recently returned from the Middle East said Russia is believed to have struck a tentative deal to sell the S-300 to the Islamic regime. There are reports that Russia has already moved some basic components for the system to its close ally Belarus, ready for possible transfer to Iran.

"Moscow cannot simply threaten to strike the deal," the official told The Sunday Telegraph. "Iran certainly thinks it has a deal. And the Israelis believe that a deal has been reached but that they can still block it."

The outgoing Israeli prime minister Ehud Olmert is expected to pass that message on to his counterpart Vladimir Putin and President Dmitri Medvedev when he visits Moscow next month. Israel has already ended military assistance to Georgia in an effort to placate Russia.

Russia has denied previous assertions by senior Iranians that a deal has already been finalised on the S-300.

Dan Goure, a long-time Pentagon adviser, said: "If Tehran obtained the S-300, it would be a game-changer in military thinking for tackling Iran. That could be a catalyst for Israeli air attacks before it's operational."

Dr Friedman said that if it became operational, it would effectively rule out Israeli air raids and seriously complicate any US aerial bombardment.

The system would take up to a year to become operational. In the meantime, Israel would come under heavy domestic pressure to launch an attack on Iranian nuclear plants, which the West believes are part of a secret atomic weapons programme but which Tehran claims are for civilian energy.

A senior Iranian military commander warned yesterday that any attack on Iran would start a major conflict. "Any aggression against Iran will start a world war," deputy chief of staff for defence publicity, Brigadier General Masoud Jazayeri, said in a statement. "The unrestrained greed of the US leadership and global Zionism... is gradually leading the world to the edge of a precipice."

Arms supply to Georgia must be stopped - Russian FM
September 1, 2008, 12:26

Russia’s Foreign Minister Sergey Lavrov called for an embargo on arms supplies to Georgia, as they might lead to further escalation in the region. Lavrov was addressing students of the country's top university for future diplomats on the ‘Day of Knowledge’, which marks the start of the new academic year in Russia.

“Russia has set a new standard of reacting to [Georgian - South Ossetian] circumstances, in full accordance with international law,” Lavrov told students of the Moscow State International Relations Institute.

“For a start, it would be a right step to place an embargo on weapons exports to Georgia until it is run as a normal country. We are interested in closely cooperating with the OSCE and the UN in order to guarantee security in South Ossetia and Abkhazia, as stated in the six principles signed by Presdent Medvedev and President Sarkozy”.

To read Lavrov's full address to students follow the link.

Russia’s FM also promised that Russia will continue to take measures to punish those guilty and to guarantee that the Georgian regime will never do any more harm.

Lavrov vowed that Russia wouldn’t get involved in confrontation in the international arena as its relations with NATO are now entering the ‘moment of truth’ stage.

He also spoke on Russia’s relations with Germany and the U.S., with whom Russia will build relations ‘only on a mutually honest basis’.

“Russian-German reconciliation [after World War II] is one of the most important factors in building a new Europe. We will not allow anyone to drive a wedge between our two nations,” said Lavrov

Angry North Korea threatens nuclear U-turn
Link

(CNN) -- North Korea said Tuesday it has stopped disabling its nuclear plants and will consider restoring them because the United States has not removed it from a list of states that sponsor terrorism.

N. Korea demolished the cooling tower at its main reactor complex in Yongbyon in June.

The communist nation said it halted the dismantling of the plutonium-producing plants on August 14, the state-run Korean Central News Agency (KCNA) reported.

The North "will consider soon a step to restore the nuclear facilities in (Yongbyon) to their original state," the North Korean Foreign Ministry said in a statement that KCNA carried.

North Korea agreed to a complete dismantling of its Yongbyon nuclear complex by October. In return, U.S. President George W. Bush said he would lift some U.S. sanctions against North Korea and remove it from a State Department list of state sponsors of terrorism.

The sticking point between the two countries involves verification.

Washington said last week it will not remove North Korea from the terrorism list until Pyongyang agrees to set up an internationally recognizable mechanism to verify its declaration.

The U.S. has demanded that inspectors be given the right to visit all suspected nuclear facilities without notice, the South Korean news agency, Yonhap, said.

North Korea rejects that provision.

"The U.S. is gravely mistaken if it thinks it can make a house search in (North Korea) as it pleases just as it did in Iraq," the Foreign Ministry statement said.

In June, North Korean officials turned over to China a 60-page declaration, written in English, that details several rounds of plutonium production at the Yongbyon plant, dating to 1986.

In it, North Korea acknowledges producing roughly 40 kilograms of enriched plutonium -- enough for about seven nuclear bombs, according to the U.S. State Department.

Soon after, North Korea publicly destroyed a water cooling tower at the Yongbyon facility.

North Korea agreed to abandon its atomic weapons program on a promise that it would receive energy aid equivalent to one million tons of heavy fuel oil from the five nations involved in the disarmament talks: the United States, South Korea, China, Japan and Russia.

The parties to the talks also agreed on a system for verifying North Korea's compliance, including "visits to facilities, review of documents, interviews with technical personnel and other measures unanimously agreed upon among the six parties," according to a joint statement they released.

The North Korean Foreign Ministry said Tuesday that the United States was in "outright violation" of the agreement.

"The U.S., however, raised all of a sudden an issue of applying an 'international standard' to the verification of the nuclear declaration, abusing this agreed point," the statement said. "It (pressured North Korea) to accept such inspection as scouring any place ... as it pleases to collect samples and measure them."

South Korea's Foreign Ministry said it was disappointed by its neighbor's decision.

"The measure is regrettable as it came at a time when the six parties have to make concerted efforts to complete phase two of the denuclearization process," the ministry's spokesman Moon Tae-young told reporters.

He said Seoul "will work closely with relevant countries to have North Korea resume the disablement work as early as possible."
