SLAC Scanner Processor Applications in the Data Acquisition System for the Upgraded Mark II Detector

The SLAC Scanner Processor is a general purpose, programmable FASTBUS crate/cable master/slave module. This device plays a central role in the readout, buffering and preprocessing of data from the upgraded Mark II detector´s new central drift chamber. In addition to data readout, the SSPs assist in a variety of other services, such as detector calibration, FASTBUS system management, FASTBUS system initialization and verification, and FASTBUS module testing.
