Hadron

Europe's Large Hadron Collider has started up its proton beams again at unprecedented energy levels after going through a three-year shutdown for maintenance and upgrades.It only took a couple of days of tweaking for the pilot streams of protons to reach a record energy level of 6.8 tera electronvolts, or TeV. That exceeds the previous record of 6.5 TeV, which was set by the LHC in 2015 at the start of the particle collider's second run.  The new level comes "very close to the design energy of the LHC, which is 7 TeV",…

The Large Hadron Collider (LHC), the largest and most powerful particle accelerator ever built, is ready to go back into service after a three-year overhaul and refit. On April 22, 2022 at 12:16 pm CEST, two proton beams with an injection energy of 450 GeV were sent in opposite directions around the the 27-kilometer-long (17-mile) ring.The advantage of a giant atom smasher like the LHC is that the tremendous energies it can impart on subatomic particles can cause them to strike each other so hard that they break apart in…

Scientists at Europe's physics research centre will this week fire up the 27 kilometer-long Large Hadron Collider (LHC), the machine that found the Higgs boson particle, after a shutdown for maintenance and upgrades was prolonged by COVID-19 delays.Restarting the collider is a complex procedure, and researchers at the CERN centre have champagne on hand if all goes well, ready to join a row of bottles in the control room celebrating landmarks including the discovery of the elusive subatomic particle a decade ago."It's not…

The Large Hadron Collider restarted Friday after a three-year break for upgrades that will allow it to smash protons together at even greater speeds, in the hope of making new ground-breaking discoveries.It will further study the Higgs boson, the existence of which it proved in 2012, and put the Standard Model of particle physics to the test after recent anomalies sparked theories about a mysterious fifth force of nature."Two beams of protons circulated in opposite directions around the Large Hadron Collider's…

With its proton beams, the newly enhanced Large Hadron Collider (LHC) set a new world record. The LHC, which is housed at CERN near Geneva, Switzerland, reopened on April 22 after a planned three-year sabbatical during which the facility was upgraded. These improvements are already being put to the test, and the LHC has already broken a previous record in restarting and preparing for its new working phase, known as Run 3. This particle accelerator is the world's biggest and most powerful. The LHC accelerated protons to…
