The International Committee for Future Accelerators (ICFA), which is responsible for the construction of a new collider, the next-generation particle accelerator , made a number of recommendations on reducing the size of the future structure and reducing its power by half. Some of the scientists found these recommendations very strange and disappointing in the light of the fact that in the experiments at the Large Hadron Collider (LHC) , even traces of new, previously unknown particles, ceased to appear in the last few months . In other words, the BAC has almost completely exhausted all its capabilities, despite the modernization not so long ago and increasing the capacity of the accelerator .
Scientists associate hopes for further advancement of the field of particle physics with the new linear accelerator-collider International Linear Collider, which will be built in Japan and which should be commissioned, according to plans, in 2030. The reduction in the size of the future accelerator proposed by the ICFA committee will help reduce the costs of excavation and other overhead costs. This, plus a reduction in the power of the accelerator, should reduce the total amount by 40 percent of the original.
“The International Linear Collider (ILC), which will operate at mass-energy level up to 250 GeV, is able to provide high-precision measurements necessary for studying the phenomena associated with the Higgs boson,” the ICFA representatives write.
It is assumed that the ILC collider will work somewhat differently than the Large Hadron Collider. Instead of proton rays in the ILC collider, electrons and their “antipodes” from the side of antimatter will collide – positrons, dispersed by electric magnets with cryogenic superconducting windings. According to the original plans, the length of the straight tunnel of the accelerator ILC should have been 10 kilometers, but in the light of the latest recommendations it can be reduced by half.
The ILC project was originally estimated at $ 10 billion. Such a project in conditions of the current economic situation is beyond the forces of any single country, it can be realized only with the joint participation of the majority of highly developed countries – world leaders.
Reducing the power from 500 to 250 GeV will leave the physicists with the opportunity to study the phenomena associated with the Higgs boson. However, behind the new energy threshold there will already be the heaviest quarks, true quarks. However, greater power and a greater level of particle acceleration energy can be obtained later by upgrading the existing accelerator design.
All of the above is for the time being only preliminary, and the time when the construction of the ILC accelerator will begin in Japan, it may not yet come soon or never at all. In the meantime, the European Organization for Nuclear Research CERN, which manages the Large Hadron Collider, is plotting to build an even larger ring collar, the Future Circular Collider, with a tunnel length of 60 miles (about 100 kilometers ). So the future of elementary particle physics is not as gloomy as it might seem at first sight.
