CERN plans to build a collider that is 3 times larger and 7 times more powerful than LHC
Next week, the first meeting of the CERN working group on the creation of a new collider will take place in Geneva. It is assumed that the length of its circumference will be from 80 to 100 km versus 26.7 km of the Large Hadron Collider, and the maximum energy of the accelerated particles will be about 100 teraelectronvolts versus 14 TeV at the LHC. When exactly will the new collider be built, and what will be its exact characteristics, for now it is too early to speak. For comparison, 25 years have passed from the start of work on the BAK project to its commissioning.
In the short term, the Large Hadron Collider is still in the center of attention of physicists. Now it is undergoing technical work. Their goal is to increase the particle energy from the current 8 TeV to the design 14 TeV and install additional equipment on the detectors. That is, strictly speaking, even the LHC itself is not yet fully completed. The next milestone after reaching the design capacity is an upgrade of the collider to increase the luminosity (this is the name of the accelerator parameter characterizing the number of collisions of a particle beam with a target or oncoming beam). It is planned to increase the luminosity tenfold.
The energy of 100 TeV is so high that it is already possible to choose analogs in the macrocosm. Approximately a grain of rice that fell from a height of 10 cm has such kinetic energy. The energy of a single proton in the Large Hadron Collider of Physics was compared with the energy of several flying mosquitoes. However, these energies look modestly next to the energies of particles, which are sometimes found in the composition of cosmic rays. So, in 1991, a particle, presumably, a proton, with an energy of 3x10 8 TeV, or 50 joules, was registered . This is comparable to the energy of a baseball, flying at a speed of 100 km / h.
