	The electron beam in the Diamond Synchrotron Light Source is stabilised in two planes using the Fast Orbit Feedback system. This feedback system takes the beam position from 168 Libera electron beam position monitors, for both planes, and calculates offsets to 336 corrector power supplies at a sample rate of ~10 kHz. The design and realisation, together with system performance will be presented, and possible developments considered.
THP011	The Diamond Light Source Control System Interface to the Libera Beam Position Monitors	694
	M. G. Abbott, G. Rehm, I. Uzun Diamond, Oxfordshire
	Libera Electron Beam Position Monitors (EBPMs) used at Diamond provide information about the electron beam position at a variety of frequency scales from 10MHz, through revolution frequency, down to 10Hz. Diamond Light Source has implemented an EPICS interface to the Libera BPMs to integrate all of this information into the overall control system. Using this, in conjunction with the timing and fast orbit feedback interfaces, provides access to all the rich data sets and functionality provided by Libera. The details of the interface, data available, both directly from the Libera and through a data concentrator will be presented.
