Cern’s Large Hadron Collider (LHC) is currently in a state of long-term shutdown and is undergoing a massive upgrade, with countless scientists eager to see the “king” return soon. According to CERN’s official website recently reported that the agency’s management submitted to the council on the 12th of the new schedule shows that the LHC will be restarted in May 2021, and until the end of 2024. A new round of upgrades will be launched in 2025 until the “high-brightness LHC” is “shining” in 2027.
The LHC is by far the largest particle collider ever built by humans, and the discovery of the Higgs boson, known as the “God Particle”, in 2012 made a worldwide sensation. Over the years that followed, the LHC continued to push particle physics forward: the Hyperloop Instrument Experiment (ATLAS) and the Compact Muse Coil Experiment (CMS) gave scientists a deeper understanding of the nature of the Higgs boson; The charge-mass destruction phenomenon in double-tweezers and quarks, and the Large Ion Collider Experiment (ALICE) reveals phenomena that have never been observed before in nuclear matter.
But the LHC’s energy and ambitions don’t stop there, and CERN decided to upgrade it to maximize its operational potential. On December 3, 2018, local time, the LHC Phase II was completed and entered the second long shutdown phase to begin the installation and commissioning of the upgrade plan. Over the past year, scientists and engineers have been working hard to upgrade the accelerator complex and major experiments to prepare for the LHC Phase III and to prepare for the arrival of his successor, the High Brightness LHC. All machines and infrastructure will be upgraded: the entire particle accelerator chain has been completely refurbished, a number of new equipment is being installed, and many of the experimental components of the four experiments of ALICE, ATLAS, CMS and LHCb will be replaced.
It is reported that after the upgrade, the LHC will be “refreshed”, proton beam collision energy will jump from 13TeV (tai electron volt) to 14TeV, collision capability will also be improved.
After the third phase of operation, the LHC will enter its third long shutdown phase in 2025. Engineers will then install the equipment needed for the High Brightness LHC in preparation for its shiny debut by the end of 2027.
The successor, the High Brightness LHC, will produce more collisions than the LHC, and is expected to accumulate more than 10 times the amount of data accumulated over the entire operational period. As a result, this unprecedented device is expected to observe extremely rare physical phenomena and greatly improve measurement accuracy. To take full advantage of the vast amount of data provided by the High Brightness LHC, the LHC’s four major experiments have also embarked on ambitious probe upgrades.
