A VME based quench protection monitor for the Tevatron low beta quadrupoles

A VME based quench protection monitor system has been designed and installed at both low beta locations in the Tevatron. Fixed-target and collider mode operations have been successful. One VME based system protects all of the high current circuits in each building rather than one Multibus I system per circuit as is the case for other Tevatron quench protection monitors. The software has been written in C for portability and flexibility for possible use with other magnet systems. Object oriented communications with the ACNET control system are made via the Token Ring network
