Prototype Results with a Complete Beam Loss Monitor System Optimized for Synchrotron Light Sources

Beam loss monitors in synchrotron light sources are finding an increasing utility in particular with the trend of numerous light sources pushing to lower emittances and thus higher intra-beam scattering, while operating in top-up injection modes and employing in-vacuum undulators in their rings. The development of an optimized electron BeamLoss Monitor aims at fulfilling, in one single system, all possible functionalities and applications like both the measurement of fast-time-resolved losses at injection and the possibility of ultra-sensitive detection of low & slow electron loss level variations. This optimized beam loss monitor system comprises both the acquisition electronics and up to four sensor head per unit. The sensor heads themselves, that can be configured for different sizes or volumes, are based on the detection of the electromagnetic shower resulting from an electron loss through the use of either Cherenkov radiator or gamma scintillator and a photomultiplier tube, all assembled in a single compact housing ready for installation.
