The CERN accelerator complex is presently undertaking a long period of shutdown, meant to consolidate and upgrade its availability and performance. The Large Hadron Collider (LHC) operation relies on 1232 superconducting dipoles and 400 superconducting quadrupoles powered at 12 kA, operating in superfluid He at 1.9 K. A sophisticated magnet protection system allows safe energy extraction in case o ... More

The front end means the front part of linac that includes IS, LEBT, RFQ and MEBT. As the start point of CSNS, the condition of front end is one of key factors which influence the stable operation of CSNS. Based on the beam requirement of CSNS phase I, the front end should provide a stable H- beam with energy of 3.0MeV, a maximum pulsed peak current up to 15mA, a beam duty factor 1.0% at a repetiti ...

Hefei Light Source (HLS) successfully completed its major upgrade project in 2014. The lattice structure is changed from TBA to DBA while the circumference remains 66 m due to the limitation of the facility building. The beam energy is kept 800 MeV and the current is raised to 360 mA. The upgrade greatly improved the performance of the light source including its stability and reliability. However ... More

By combining data from laser trackers and laser scanners we can develop 3D models of an accelerator system as it is built. This allows more precise shielding installations, higher tolerancing of equipment placement and a more productive design environment. Scans of areas are taken during beam off periods and combined with other alignment parameters. The designers can use this information to accura ... More

We aim to recover the machine faults as quickly as possible to provide a stable beam of good quality. But preventing the machine faults is more important. To do that, we had to make ‘warning signal’ about getting out of the stable range. And when the operator's direct action is needed immediately, the appropriate range and logic are made to generate a warning signal for each device by using so ... More

Operations group have developed and used a Microsoft Access based fault database since we started commissioning Diamond in 2006. Inconsistent update of responses and corrections sent be email or posted in the main log often results in information about the faults being lost, meaning a new more integrated approach was desired. In addition concerns with the lack of change history and granular contro ... More
