/ Morales Vigo, Sara (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Salvachua, Belen (CERN) ; Welsch, Carsten (Cockcroft Inst. Accel. Sci. Tech.) ; Zamantzas, Christos (CERN) ; Calvo Giraldo, Eva (CERN) ; Martinez Samblas, Javier (CERN) ; Wolfenden, Joseph (Cockcroft Inst. Accel. Sci. Tech.) ; Gonzalez-Berges, Manuel (CERN)
A set of twelve Polycrystalline Chemical Vapour Deposition (pCVD) diamond detectors are installed in the beam injection, extraction and betatron collimation areas of the Large Hadron Collider (LHC) as fast beam loss monitoring detectors. Their high-radiation tolerance and time resolution in the order of a few ns makes them an ideal candidate to monitor bunch-by-bunch losses in the LHC beams, which have a nominal bunch separation of 25 ns.

Accel. Sci. Tech.) ; Wolfenden, Joseph (Cockcroft Inst. Accel. Sci. Tech.) et al.
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. [...]
