Automation of control of the U-400 cyclotron multicharged ion source

An arc ion source with a heated cathode and cathode sputtering of the working substance (MCIS) is used at the JINR LYaR U-400 cyclotron to produce multicharged ion beams. To increase the efficiency of studies with multicharged ions, os stable beam production and to ensure the optimum operation modes of the source the necessity of on-line control over its parameters using hardware arose. Control microprocessor subsystem on the basis of CAMAC apparatus was developed, which has become a part of the on-line system for parameter control. The subsystem comprises two CAMAC crates - resident and MCIS control ones - each of them containing the KM001 built-in microcomputer. The resident crate ensures dialogue interaction with an operator and transmits commands to the control crate, it is also used for communication with the SM-4 minicomputer. The software is realized using the ASSEMBLER language and the INTEL 8080 processor
