Control system of the RIKEN SSC

The RIKEN SSC facilities consist of two injectors, HI linac-AVF cyclotron and a separated-sector cyclotron. This system is controlled by means of three mini-computers, which are linked with one another through an optical fiber loop. A CAMAC serial crate network and a GP-IB are used for the control of accelerator devices. Two types of intelligent modules have been developed; one is a CAMAC module and the other is a terminal for high speed local control of the accelerator devices. The operating system OS60/UMX is a combination of a real time and a UNIX system. Application programs are written in FORTRAN 77 language. One of the three computers was already installed in August, 1984, and has been used for the program and data base development. (author)
