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. [...]

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.

A prototype of a Beam Loss Monitor based on the detection of Cherenkov light in optical fibres is being developed to measure beam losses in the CERN Super Proton Synchrotron. Several testing campaigns have been planned to benchmark the simulations of the system and test the electronics in the CLEAR facility at CERN. [...]

The European Spallation Source (ESS) to be under construction in Lund, Sweden, will provide a highest average intensity beam from a 5 MW superconducting proton linear accelerator to produce spallation neutrons. A serious problem for high current accelerators is the high density of the beam, which is able to destroy the equipment, to make a quench of super conductive magnets [...]

Fast Spill Monitor Studies for the SPS Fixed Target Beams
/ Roncarolo, Federico (CERN) ; Arrutia Sota, Pablo Andreas (CERN) ; Belohrad, David (CERN) ; Bergamaschi, Michele (CERN) ; Calvo Giraldo, Eva (CERN) ; Effinger, Ewald (CERN) ; Fraser, Matthew (CERN) ; Kain, Verena (CERN) ; Martin Nieto, Miguel (CERN) ; Mazzoni, Stefano (CERN) et al.
At the CERN Super Proton Synchrotron (SPS) the proton beam is supplied to the fixed target experiments in the North Area facility (NA) via a slow extraction process, taking place at 400 GeV. The monitoring of the spill quality during the extraction, lasting 4.8 seconds with the present SPS setup, is of high interest for minimising beam losses and providing the users with uniform proton-on-target rates.

The Diamond Beam Loss Monitoring System at CERN LHC and SPS

The Large Hadron Collider (LHC) and the Super Proton Synchrotron (SPS) accelerators are equipped with 17 pCVD diamond based Beam Loss detectors at strategical locations where their nanosecond resolution can provide insights into the loss mechanisms and complement the information of the standard ionization chamber type detectors. They are used at the injection and extraction lines of the LHC and SPS, to analyse the injection or extraction efficiency, and to verify the timing alignment of other elements like kicker magnets.
