Cover Story: Optical Beam Loss Monitors (oBLMs) allow for the cost-efficient and spatially continuous measurement of beam losses at accelerator facilities. They consist of an optical fibre parallel to the beamline, coupled to photosensors—either silicon photomultipliers or photomultiplier tubes—at one or both ends. This paper investigates and compares multiple techniques for extracting timing and position information from measured loss waveforms. For the oBLM studied, the optimal approach was found to be applying constant fraction discrimination to the upstream readout, with both tested photosensor types exhibiting similar position resolutions. These findings can be used to improve the loss position resolution of similar oBLMs by 10% or more without requiring any physical modifications. View this paper
