Abstract
The computer control system for the Fusion Materials Irradiation Test Facility (FMIT) prototype accelerator was designed using distributed intelligence driven by a distributed database. The system consists of two minicomputers in the central control room and four microcomputers residing in CAMAC crates located near appropriate subsystems of the accelerator. The system uses single vendor hardware as much as practical in an attempt to minimize the maintenance problems. Local control consoles are an integral part of each node computer to provide subsystem checkout. The main console is located in the central control room and permits one-point operation of the complete control system. Automatic surveillance is provided for each data channel by the node computer with out-of-bounds alarms sent to the main console. Report by exception is used for data logging. This control system has been operational for two years. The computers are too heavily loaded and the operator response is slower than desired. A system upgrade to a faster local-area network has been undertaken and is scheduled to be operational by conference time.
Highlights
The Fusion Materials Irradiation Test Facility (FMI1) was to be a faclllty to produce high e~ergy neutrons to aid In the development of suitable materials for the fabrication of controlled thermonuclear rea:tors, This facility was to be built at the Hanford Engineering Development Laboratory (HEDL) at Richland, Washington
A prototype of the injector, radto-frequency quadruple (RFQ), and a port!on of the drift-tube ]~nac tank Wds built at Los Alamos
The supervisory control system for the prototype accelerator was to be prototypical of the final system to be Installed at HEDL
Summary
The Fusion Materials Irradiation Test Facility (FMI1) was to be a faclllty to produce high e~ergy neutrons to aid In the development of suitable materials for the fabrication of controlled thermonuclear rea:tors, This facility was to be built at the Hanford Engineering Development Laboratory (HEDL) at Richland, Washington. A prototype of the injector, radto-frequency quadruple (RFQ), and a port!on of the drift-tube ]~nac tank Wds built at Los Alamos. The prototype accelerator was designed to produce a 100-mA continuous wave (CW) deuteron beam at 5 MeV. The supervisory control system for the prototype accelerator was to be prototypical of the final system to be Installed at HEDL. The contro”system design needed to be versatile and expandable to support both accelerator development and operatiof~of a “neutron factory” at HEN.
