The LCLS-II (Linac Coherent Light Source II), a revolutionary new X-ray laser, is currently being built at SLAC National Accelerator Laboratory. The LCLS-II Vacuum System consists of a combination of particle free and non-particle free areas and includes the beamline vacuum, RF system vacuum, cryogenic system vacuum and supporting systems vacuum. The Vacuum Control System includes the controls and monitoring of different types of gauges, pumps and residual gas analyzers (RGA). The Vacuum Control System uses Allen Bradley PLC (Programmable Logic Controller) to perform interlocking to isolate bad vacuum areas. In particle free areas, a voting scheme is implemented for slow and fast shutter interlock logic to prevent spurious trips. Additional auxiliary control functions and high level monitoring of vacuum components is reported to global control system via an Experimental Physics and Industrial Control System (EPICS) input output controller .This paper will discuss the design and status of the LCLS-II Vacuum Control System.
