COUNTDOWN LHC COUNTDOWN TEST FOR ZERO RISK EXPERTS
ROME - The Earth does not run any risk of being destroyed by the test to be held at CERN in Geneva next September 10 when the most powerful particle accelerator in the world, the LHC will be circulated the first beam of protons. In support are the president of the National Institute for Nuclear Physics president Roberto Petronzio and the National Research Council (Infn), Luciano Maiani, who was director general of CERN from 1999 to 2003. With the decision of the European Court of Human Rights rejected an appeal by a group of scientists, according to which it might create a mini black hole that can suck up our planet, Part as the official countdown. INFN addition to having participated in the production of the LHC, with its scientists taking part in the tests, for which also covers the roles of international responsibilities. Petronzio states that in any case, the risk is not about what will happen on 10, when there will be clashes of particles will be fed to the machine but the first beam of protons will be spun in acceleration. With regard to the subsequent tests, when beams of particles will collide at very high temperatures to recreate the conditions of the Big Bang, according to Einstein's relativity, said Petronzio, there is no danger. "Already in 2003 - said Petronzio - CERN has created a group evaluation for the safety of LHC has reassured us that the safety of products in acceleration experiments. The same opinion was also expressed by the group of scientists Scp Scientific Policy Committee, which includes Nobel Prize for Physics expressing scientific assessments for the Council of CERN. "If this were not enough, says Petronzio, more evidence that refutes the black hole theory of risk are constant, harmless, high-energy collisions that take place in the universe, as cosmic rays hitting the Earth. The absence of risk by the tests of the LHC, is also underlined by Maiani. E 'was right to address the problem - he said - but the problem has no basis as to cause concern. From scientific point of view, however, are fully convinced that the results of the experiment will be in the positive sense. "WAITING smoothly THROTTLE START - Just a few days and the giant particle accelerator will" wake up ": the first beam of protons will travel the 27 km ring of the Large Hadron Collider (LHC) Wednesday, September 10. Everything is proceeding smoothly and make you smile assumptions catastrophe recent days, while growing by the hour waiting for this' event between the researchers at CERN in Geneva. "Some of us are working on this project for nearly two decades and now we are full of hope, there is a very nice atmosphere," says physics Maria Curatolo, director of physical Italian for Atlas, one of the four major experiments that will be conducted nell'Lhc. "The test injection started in August have been completed and all went well," he says. Wednesday, 10, finally, we will proceed to the next step: "Once injected into an 'accelerator particle beams will circulate around the ring." Initially, the energy intensity is quite low compared to that provided in the scheme: 450 GeV (or 450 billion electron volts), which soon will be extended to five TeV (5,000 billion electron volts) and then to seven TeV (7 trillion electron volts). "In these days - says Curatolo - all tests are in progress which will continue until the last time. Everything is under control and we know that September 10 the world's attention will be bet on the accelerator. "Meanwhile, he adds," is already a great satisfaction to see that it's been implemented and is operating a machine that represents a real frontier of technology. "Everyone at CERN, are aware of the fact that the LHC accelerator is a complex and difficult." for this reason in recent years there has been some delay and the expected date for commencement of operation has been postponed several times. But now everything is finally ready and we are all waiting. "Hope and confidence are the most common state of mind, those that shine ever more evident: "We are all hopeful. We know that scientists working on the machine years done a great deal and now the situation has reached the end point. We are very confident that now has begun the phase we have been waiting a long time and where we can take all the necessary data to explore a new horizon physics.
