The Control System of the 5045 Klystron Modulator on the Basis of the CompactRIO System

The control system of the 5045 klystron modulator that is used in the VEPP-5 injection complex of the Budker Institute of Nuclear Physics (BINP, Novosibirsk) is described. The system is constructed on the basis of a built-in CompactRIO chassis (National Instruments) with a set of modules. Some of these modules are being developed at the BINP. The chassis with an auxiliary computer and a standby power supply is assembled in a 19'' frame with a height of 3U. The software for the modulator control, protection, and monitoring was developed in the LabVIEW environment. The system is integrated into the general control system of the injection complex on the basis of EPICS. A support of the CX server that was developed at the BINP was used at the chassis-controller level.
