Being responsible for 3 GeV booster synchrotron for the National Synchrotron Light Source (NSLS-II, BNL, USA) design and manufacture, Budker Institute of Nuclear Physics also designs the booster control and diagnostic system. Among others, the system includes interlock system consisting of equipment protection system, vacuum level and vacuum chamber temperature control system, beam diagnostic service system. These subsystems are to protect facility elements in case of vacuum leakage or chamber overheating and to provide subsidiary functions for beam diagnostics. Providing beam interlocks, it processes more then 150 signals from thermocouples, cold and hot cathode vacuum gauges and ion pump controllers. The subsystems contain nine 5U 19" chassis with hardware of each based on Allen-Bradley CompactLogix Programmable Logic Controller. All the interlock related connections are made with dry contacts, whereas system status and control is available through EPICS channel access. All operator screens are developed with Control System Studio tooling. This paper describes configuration and operation of the booster interlock system.

The National Synchrotron Light Source II (NSLS-II) is a state-of-the-art 3 GeV third generation light source currently under integrated testing and commissioning at Brookhaven National Laboratory. The vacuum systems are monitored by vacuum gauges and ion pump current. The gate valves are controlled by programmable logic controllers (PLC) using voting scheme. EPICS application codes provide the high level monitoring and control through the input-output controllers. This paper will discuss the commissioning status of the various aspects of vacuum control system.

Residual Gas Analyzers (RGAs) have been widely used in accelerator vacuum systems for monitoring and vacuum diagnostics. The National Synchrotron Light Source II (NSLS-II) vacuum system adopts Hiden RC-100 RGA which supports remote electronics, thus allowing real-time diagnostics with beam operation as well as data archiving and off-line analysis. This paper describes the interface and operation of these RGAs with the EPICS based control system.
