Waveguide Air Pressure Interlocks Low   ACIS Interface Yes.  RSS Boundary = Protection from rf radiation from opening in the rf waveguide system by detecting a drop in slight positive air pressure maintained inside the waveguide system by the rf cavity coupler air blowers.  The system consists of 9 separate calibrated Photohelic air pressure guages installed at various positions in the waveguide system throughout Building 420. The alarm outputs of all Photohelic pressure guages (except for the Photohelic pressure gauge located at the 350MHz RF Test Stand, which is presently disabled) terminate at an interface chassis that routes shutdown commands to the RF Personnel Safety Interface Chassis all Storage Ring and Booster RF stations (RF1-TF5) in the event any single or comination of the Photohelic pressure guages rgisters an alarm. The RF Personnel Safety Interlock System at each rf station in turn disables the HVPS and klystron rf drive. ASD/RFG      
350MHz RF Test Stand RF Radiation Monitor Medium   ACIS Interface Yes. RSS Boundary = This rf radiation monitor provides an alarm contact closure to the 350MHz RF Test Stand ACIS system in the event the rf radiation level behind the test stand operator console exceeds approximately 0.10mW/sq-cm at 351.93MHz. ASD/RFG      
350 MHz RF Test Stand Bunker Isolation Waveguide Medium   ACIS Interface Yes.  RSS Boundary = Two full-height WR2300 waveguide shutters that provide rf isolation in the waveguide system for downstream personnel protection when the test cavity or connecting waveguide is disassembled for analysis, repair, or modification. The open/closed position of the waveguide shutters is monitored by the 350MHz RF Test Stand ACIS system utilizing dedicated position indication switches installed inside each waveguide shutter.  These position indication switches provide contact closures to the ACIS system through dedicated connectors and cabling from each shutter.  The 350MHz RF Test Stand ACIS system monitors the position of both waveguide shutters and uses the shutter position to either permit or inhibit the operation of RF1.  Both of these waveguide shutters are equipped with Kirk-interlock systems that allow the shutters to be locked in the closed position for LOTO purposes. The position of both of these waveguide shutters can be changed manually or by remote control from the 350MHz RF Test Stand PLC Control System.  ASD/RFG      
350MHz RF Test Stand 1MW RF Test Load Isolation Waveguide Shutters Medium   ACIS Interface Yes.  RSS Boundary = Two full-height WR2300 waveguide shutters that provide rf isolation in the waveguide system for downstream personnel protection in the connecting waveguide run between switch #4, the device test circulator, and the 1MW rf test load is disassembled for analysis, repair, or modification.  Both of these waveguide shutters are equipped with Kirk-interlock systems that allow the shutters to be locked in the closed position for LOTO purposes.  The position of both of these waveguide shutters is changed manually, or electrically by the use of local control boxes that are temporarily connected to the shutters.  ASD/RFG
