The Accelerator Report published on 10 May highlighted that the 2023 antiproton physics run was delayed by 50 days (reducing the run to 122 days instead of the 172 initially scheduled) due to a broken...
The discovery of the Higgs boson at CERN’s Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently inv...
On 11 May, four days before the original schedule had set a target of 1200 bunches per beam, the LHC made its final intensity ramp-up step to 2400 bunches per beam.
Late in the afternoon of Friday, 21 April, another important milestone was achieved in the LHC beam commissioning. At 6.58 p.m., one day ahead of schedule, the LHC Engineer in Charge declared “stable ...
CERN and the US Accelerator Upgrade Project (AUP, a consortium of various US institutions including Fermilab, BNL and LBNL laboratories based at Fermilab) are working in tandem to develop, build and t...
Although neutrinos are produced abundantly in collisions at the Large Hadron Collider (LHC), until now no neutrinos produced in such a way had been detected. Within just nine months of the start of LH...
The Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator, is also the largest single machine operating in the world today that uses superconductivity. The proton bea...
Much of the research and development work for the High-Luminosity LHC (HL-LHC) aims to protect the accelerator’s fragile components from the detrimental effects of high luminosity, such as radiation a...
When the Large Hadron Collider (LHC) is operating, it produces more than one billion proton–proton interactions every second. But exactly how many take place in the LHC experiments? Critical to every ...
The SM18 test facility, located in France, near the Meyrin site, was originally built to test and validate the magnets and radiofrequency (RF) cavities of LEP (the Large Electron–Positron Collider). I...
Future accelerator projects, including the high-luminosity upgrade of the Large Hadron Collider, will rely on niobium–tin (Nb3Sn) alloys for their superconducting components, such as electromagnets. T...
During LS2, the LHC’s two external beam dumps were removed from the tunnel and replaced with spare ones. After ten years of operation, they were showing signs of degradation, notably nitrogen leaks. B...
Update: The first pilot beams circulated in the LHC on 19 October 2021. On 26 October, there were low-intensity test collisions at an injection energy of 450 GeV per beam and stable collisions of prot...
Uppsala University in Sweden has been a valuable partner to CERN since the Laboratory’s foundation. In the 1950s, Uppsala, having just constructed its own cyclotron, contributed to the development of ...
近日,近代物理所磁铁技术室科研人员利用TCF10低温站及自建的超导磁体低温测试平台对CERN亮度升级项目(HL-LHC),斜螺线管型(CCT)双孔径超导磁体进行了测试。测试前后历时2个月,先后完成了磁体机械检测、电气检测、室温磁场测量、低温励磁测试等多项内容。HL-LHC CCT超导磁体项目由高能物理所牵头,近代物理所作为参与单位,计划与各合作单位共同完成13台(1台样机加12台正式磁体)双孔径轨...
