\n\"\" Japan\u2019s High Energy Accelerator Research Organization (KEK) has been steadily improving the performance of its flagship electron-positron collider, SuperKEKB, since it produced its first electron-positron collisions in April 2018. At 20:34 on 15th June 2020, SuperKEKB achieved the world\u2019s highest instantaneous luminosity for a colliding-beam accelerator, setting a record of 2.22\u00d71034<\/sup>cm-2<\/sup>s-1<\/sup>. Previously, the KEKB collider, which was SuperKEKB\u2019s predecessor and was operated by KEK from 1999 to 2010, had achieved the world\u2019s highest luminosity, reaching 2.11\u00d71034<\/sup>cm-2<\/sup>s-1<\/sup>. KEKB\u2019s record was surpassed in 2018, when the LHC proton-proton collider at the European Organization for Nuclear Research (CERN) overtook the KEKB luminosity at 2.14\u00d71034<\/sup>cm-2<\/sup>s-1<\/sup>. SuperKEKB\u2019s recent achievement returns the title of world\u2019s highest luminosity colliding-beam accelerator to KEK.\uff08\uff0a\uff09
\uff08\uff0a\uff09The current record is 2.40\u00d71034<\/sup>cm-2<\/sup>s-1<\/sup>, obtained at 00:53 JST on June 21st. —more<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
