Abstract :
A Cerenkov radiation detection system has been designed for Argonne National Laboratory´s Advanced Photon Source 7-GeV electron storage ring. This system is intended for monitoring and measuring localized beam losses. The Cerenkov radiation detection system includes a detector assembly mounted at selected locations in the storage ring tunnel and an electronics package in a VME format. The electronics package consists of a high-voltage power supply, a 16-bit pulse discriminator-counter, two gated integrators, and two 16-bit analog-to-digital converters. The design of the timing circuit offers an extended range of 655 μs for both the gated integrator gate width and gate delay. The detectors have been installed near all storage ring scrapers, the storage ring thin-septum magnet, and at several insertion device locations. Plans are to instrument all present and future insertion devices. This paper discusses the electronics design as well as the mechanical design of the Cerenkov detector system
