CERN announced that yesterday, when it was afternoon in Switzerland, the detectors of the Large Hadron Collider (LHC) began detecting collisions between particles at an energy that reached 13.6 TeV (Tera-electronVolts). These are energy levels never reached before, which mark the beginning of Run 3, the third LHC research campaign.

At the end of April, after the Long Shutdown 2, the period of more than three years in which the LHC equipment was updated, the slow restart of the largest particle accelerator in the world began. The detectors and other systems of the LHC experiments were updated as well to increase the quantity and quality of data that will be collected in the new research campaign.

The LHC (Large Hadron Collider), the largest particle accelerator in the world, has resumed work in preparation for the new work program, code-named Run 3, which is scheduled to start in July. The initial operations are the ones necessary to test the equipment after more than three years of update work. On April 22, the first proton beams were injected in opposite directions into the 27-kilometer the LHC ring. If all goes as planned, Run 3 will begin in July pending the completion of other works that will lead to the enhanced version called High Luminosity the LHC (HiLumi LHC or simply HL-LHC).

CERN announced that the Large Hadron Collider (LHC) successfully tested particle collisions at the highest energy level possible after its updates, 13 TeV (13 trillion electron volts). After the restart of the enormous particle accelerator took place at Easter, the energy levels were gradually increased and in Wednesday’s late night the collisions reached the maximum energy.

This Easter represented for CERN the time of the Large Hadron Collider (LHC) full operation restart. After the testing that began a few weeks ago, in the morning of last Sunday a proton beam has covered all 27 kilometers (about 17.7 miles) of the giant ring. After less than two hours, a second beam was sent in the opposite direction. The energy was “only” 450 GeV but it was a major event for the restart of the scientific activity.

CERN has confirmed that during the last weekends two of the Large Hadron Collider (LHC) experiments have successfully sent proton beams through the particle accelerator. This is the first full test of operation that marks the beginning of the last phase of restart after the equipment upgrade made during the last two years. The test, conducted by the LHCb (Large Hadron Collider beauty) and ALICE (A Large Ion Collider Experiment) experiment was a success.
