The Beam Loss Monitoring System after LHC Long Shutdown 2 at CERN
/ Saccani, Mathieu (CERN) ; Effinger, Ewald (CERN) ; Viganò, William (CERN) ; Zamantzas, Christos (CERN)
Most of the LHC systems at CERN were updated during the Long Shutdown 2, from December 2018 to July 2022, to prepare the accelerator for High-Luminosity. The Beam Loss Monitoring system is a key part of the LHC’s instrumentation for machine protection and beam optimisation by producing continuous and reliable measurements of beam losses along the accelerator.

Chemical Vapour Deposition (CVD) diamond detectors have been tested during the Run 2 operation period (2015-2018) as fast beam loss monitors for the Beam Loss Monitoring (BLM) system of the Large Hadron Collider (LHC) at CERN. However, the lack of raw data recorded during this operation period restrains our ability to perform a deep analysis of their signals. [...]
