	The 75 BPM stations of the Booster Synchrotron of the ESRF have been equiped with new RF electronics from December 2014. This new BPM system is based on the commercial Libera-Spark system and now provides beam position data at various output rates, and with a possible time resolution even below that of the orbit-turn time (1 us). All modules are situated inside the Booster tunnel and powered by an Ethernet cable. This implies that the RF cables from the BPM blocks are less then 3 m and only a single trigger signal in daisy chain is sufficient to keep the 75 stations in turn-by-turn phase over the full energy ramping (200 MeV to 6 GeV) time of typically 50 ms. The high sensitivity of the system yields excellent performance at very low beam currents down to 1 0uA. Full results of the system, including the application as a high quality betatron tune monitor, will be presented.

MOPTY041	Prototype Results with a Complete Beam Loss Monitor System Optimized for Synchrotron Light Sources	1019

	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.
