Ion Source Test Stand Vacuum Control System Johnny Tang

Hot Spare Stand Vacuum Requirements (Purpose) To maintain a suitable pressure in the LEBT for conditioning and measuring the performance of the hot-spare ion source (Vacuum Requirements) Hydrogen gas load is Torr l/s (Vacuum Requirements) To limit the charge-exchange to 10%, required 3 pump speed 1500 l/s in LEBT (not least) (Vacuum Requirements) LEBT vacuum pressure 10-6 Torr with no Gas and 10-4 Torr with H2 Gas Estimated pump down time : < 20 Minutes (Control System Requirements) –Keep the Same Functionality as in Front End –Upgrade PLC5 to ControlLogix –Upgrade RIO to EtherNet/IP –Use R3.14 EPICS Base Release

Controlled and Controlling Device List 5 Convectron Gauges (CG) 4 Ion Gauges (IG) 3 Turbo Pumps (TMP) 4 Rough Pumps (RP) 3 Gate Valves (GV) 4 Rough Valves (RV) 1 Vent Valve (VV) 2 AB-Flex IO Boxes (FEE20 & FER08-26) 1 ControlLogix PLC 1 EtherNet/IP Module 1 VME IOC FEE20: 2 IE8, 2 IB16, 1 IV16, 1 OB16 and 2 OW8 modules (76 IOs) FER08-26: 1 IE8, 1 IB16, 1 OE4 and 3 OW8 modules (36 IOs)
