There are very often spin offs in medical areas in what we do. \"\u003cbr/\u003e16. Pull out from tunnel to ground level\u003cbr/\u003eIt sounds like something straight out of science fiction - a mysterious, sub-atomic fragment that permeates the entire universe but has proven so elusive that to this day the world's top minds have been unable to prove it's existence or study it. \u003cbr/\u003eScientists in Switzerland hope to create conditions where subatomic particles, in this case protons, travel at nearly the speed of light until they collide, emitting a shower of even smaller particles that will reveal mysteries about the makeup of matter.\u003cbr/\u003eBut a recent technical hitch means the world's most ambitious particle collider might not be fully functional until next year.\u003cbr/\u003eScientists and journalists gathered at CERN headquarters on the French - Swiss border on Thursday (April 26, 2007) to witness the end of a crucial phase of the particle project. \u003cbr/\u003ePhysicists from across the world have joined forces in Switzerland to build an enormous underground tunnel, where they plan to accelerate tiny sub-atomic particles, called electrons and positrons, to near light speed and then annihilating them by smashing them into one another. \u003cbr/\u003eScientists say that such collisions replicate the conditions found just after the Big Bang and thus help increase our knowledge of how the universe was formed and what are its components. \u003cbr/\u003eA large dipole (magnetic poles of equal magnitude and opposite polarity) magnet was symbolically lowered into the tunnel. \u003cbr/\u003eThis completes the basic installation of the more than 1,700 magnets that make up the collider, which measures 27 kilometres (17 miles) in circumference. \u003cbr/\u003eRobert Aymar, director general of Cern, says it was a complicated task with very tricky logistics, because the tunnel is very narrow, and when magnets are moved in the tunnel, nobody can be in the way, nobody can work there. \u003cbr/\u003eHowever the project timetable has slipped after a key U.S.-built part of the collider broke \"with a loud bang and a cloud of dust\" during a high-pressure test last month.\u003cbr/\u003eOfficials at the organisation, known by the French initials CERN, said the possible delays are the result of the magnet failure and cooling processes that have been slower than expected for the 27-kilometre (17-mile) tunnel.\u003cbr/\u003eNow CERN admit that the November 2007 completion date is likely to slip until spring 2008. \u003cbr/\u003ePart of the delay will be due to the fact that CERN shuts its accelerators in the winter, largely to save on electricity costs.\u003cbr/\u003eLast month the first sector of CERN1's Large Hadron Collider to be cooled down had reached a temperature of 1.9 Kelvin (-271�C), colder than deep outer space. \u003cbr/\u003eBut on March 27 a magnet failed a high pressure test in the tunnel and the support structure ruptured, making a loud noise and releasing helium gas. \u003cbr/\u003eFermilab, which built the 13-metre-long (43-foot) magnet, said its teams, working with colleagues from CERN, have determined what caused the \"serious failure\" and are working on a solution. \u003cbr/\u003eThe collider has more than 1,700 magnets spaced around its circumference, the last of which was lowered into the ground on Thursday (April 26). \u003cbr/\u003eOnce the particle accelerator is up and running, the race begins to be the first to re-create the elusive particle, nicknamed 'God's particle' or the Higgs Boson particle.  \u003cbr/\u003ePhysicists have been trying to find the Higgs Boson ever since it was first proposed by Peter Higgs, an Scottish academic in the early 1960s.\u003cbr/\u003eHemar, says there is always intense competition to be the first to make a discovery, but there is also a lot of co-operation within the scientific community. \u003cbr/\u003eLike the hundreds of magnets that came before it, the final magnet was lowered 50 metres (55 yards) below the Earth's surface through a custom-built shaft with an oval cross-section.\u003cbr/\u003eIt was then conveyed via a transfer tunnel to the tunnel itself, which lies between 50 and 150 metres (164 yards) underground; once below ground, specially designed transport vehicles delivered the magnet to its final destination at 3 kilometres per hour. \u003cbr/\u003eMore than 35, 000 tonnes of material has been safely lowered underground. \u003cbr/\u003eJohan Dhote has been working on the project for two years. \u003cbr/\u003eHe says that there is a good team atmosphere and he is pleased that this stage of the project has gone well. \u003cbr/\u003eJames Gillies, a Cern spokesperson says they hope that one day the project will reveal some of the secrets of the universe. \u003cbr/\u003eGillies says that if they are successful in locating the elusive subatomic particle, the discoveries may have implications for modern medical technology such Magnetic Resonance Imaging (MRI) scans. \u003cbr/\u003eThe lab's 20 European member countries, as well as observer states like the United States and Japan, contribute to CERN's annual budget of about 1 billion Swiss francs (US$800 million;  Euro 650 million).\u003cbr/\u003eAbout 6,500 scientists from 80 countries, half the world's researchers specialising in particle physics, work at CERN, which became a main focus for world research into the nature of matter and the origins of the universe after the U.S. Congress in 1993 halted construction on the proposed Superconducting Super Collider in Texas.\u003cbr/\u003eSpin off could include advances in medicine, dating archaeological finds, destroying radioactive waste, and, eventually, finding a viable alternative clean source of energy.\u003cbr/\u003eIt's a big facility to find a small particle - but physicists hope it will help solve their long term questions about existence.\u003cbr/\u003eKeyword-science-technology\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false'
