  The momentum compaction factor of a storage ring can be obtained by measuring how the beam energy changes with the RF frequency. Direct measurement of the beam energy can be difficult, long or even not possible with acceptable accuracy and precision in some machines such as ESRF. Since the energy spectrum of the Synchrotron Radiation (SR) depends on the beam energy, it is indeed possible to relate the variation of the beam energy with a variation of the produced SR flux. In this proceeding, we will present how we obtain a measurement of the momentum compaction using this dependence.

  In view of the construction and the commissioning of the new Extremely Brilliant Source (EBS) ring, a new Beam Loss Detector (BLDs) system has been developed, installed and tested in the present European Synchrotron Radiation Facility (ESRF) storage ring. The new BLD system is composed of 128 compact PMT-scintillator based BLDs, distributed evenly and symmetrically at 4 BLDs per cell, controlled and read out by 32 Libera Beam Loss Monitors (BLMs). The detectors fast response and the versatility of the read-out electronics allow to measure fast losses with an almost bunch-by-bunch resolution, as well as integrated losses useful during the machine operation. In this paper the different acquisition modes will be explained and results obtained during injection and normal operation will be presented.
