THE DIAMOND LIGHT SOURCE CONTROL SYSTEM INTERFACE TO THE LIBERA ELECTRON BEAM POSITION MONITORS

Libera Electron Beam Position Monitors (EBPMs) used at Diamond provide information about the electron beam position at a variety of frequency scales from 10 MHz, through revolution frequency, down to 10 Hz. Diamond Light Source has implemented an EPICS interface to Libera integrating all of this information into the overall control system. In conjunction with the timing and fast orbit feedback interfaces this provides access to the rich data sets and functionality provided by Libera. The details of the interfaces and available data, both directly from the Libera and through a concentrator, are described here.
