SSRL beam position monitor detection electronics

As part of a program to improve its orbit stability, SSRL is redesigning its detection electronics for its beam position monitors (BPMs). The electronics must provide highly reproducible positional information at the low bandwidth required of an orbit feedback system. With available commercial technology, it is now possible to obtain highly resolved turn by turn information so that this electronic module can also be used to measure beam dynamics. The design criteria for this prototype system and performance of the analog section of the processor is discussed.
