The D-ZERO experiment at the Fermilab Tevatron Collider deploys approximately
1000 independently controlled high voltage channels. The VME based front-end of
the high voltage system is controlled by 68020 processors. The host processes
running on VAX/VMS computers communicate to the front-end via gateway and token
ring. The D0 Control Data Acquisition software package handles all the
messages between the host and front-end. The front-end hardware/software is
structured so as to ensure robustness and flexibility. The host software
provides an intelligent and intuitive high level control and monitoring of all
the D0 high voltage channels. The high level control of high voltage
helps optimize the response of D0 detector components.
