Automated Analysis of the Prompt Radiation Levels in the CERN Accelerator Complex

The CERN injector complex is essential in providing high-energy beams to various experiments and to the world’s largest accelerator, the Large Hadron Collider (LHC). Beam losses linked to its operation result in a mixed radiation field which, through both cumulative and single-event effects poses a threat to the electronic equipment exposed in the tunnel. Therefore, detailed knowledge of the radiation distribution and evolution is necessary in order to implement adequate Radiation to Electronics mitigation and prevention measures, resulting in an improvement of the accelerator efficiency and availability. In this study, we present the automated analysis scheme put in place to efficiently process and visualise the radiation data produced by various radiation monitors, distributed at the four largest CERN accelerators, namely the Proton Synchrotron Booster, Proton Synchrotron, Super Proton Synchrotron, and the LHC, where a proton beam is accelerated gradually from 160 MeV up to 7 TeV.
