	A new magnet power supply controller is currently being designed for Diamond Light Source. The design uses DSP based regulation implemented in an FPGA. An embedded ARM processor is used to provide integration with the supervisory control system. Interfaces are also provided for integration with the fast orbit feed back system and for synchronous control of multiple supplies. Details of the architecture and progress in the realization will be presented.
THB003	Diamond Light Source Electron Beam Position Feedback: Design, Realization and Performance	650

	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.
THP009	Developments in the Integration of Video Into EPICS on Diamond Light Source	688

	Firewire (IEEE1394) video cameras, compliant with the IIDC/DCAM specification are used on both the accelerators and photon beamlines on Diamond Light Source. Initially the integration was through a commercial Firewire/IIDC stack running on VME and VxWorks based EPICS IOCs. Recent developments have migrated the Firewire camera interface to X86 Linux based IOCs using the open source libraries dc1394 and EPICS areaDetector. The motivation for this and the software structure is described.
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.
