1. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 XTOD Vacuum Controls Final Design Review Steve Lewis/Keith Kishiyama 13 March 2008

2. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 2 Some Guidelines Re-use existing LCLS or planned XES technology when feasible Lower cost and schedule risk Reduce maintenance cost and overall complexity Else use SNS technology as ‘best-practices’ example Recent; working; EPICS-based FEE has very limited physical space, but ‘acceptable’ radiation levels Place short racks under beamline (with short cable runs) for instruments Use full-height racks in alcove for vacuum controllers XRT will use short racks for vacuum

3. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 3 Introduction There are three types of systems ‘Standard’ beamline Diagnostic ‘tanks’ (for instruments) High pressure/high flow regions (gas detector/gas attenuator) PLC vs EPICS PLC will provide protection (basic interlocking) using direct signals (analog, digital) EPICS will provide sequencing (via PLC and serial communications to controllers) LCLS Standards will be indicated with: √

4. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 4 Common Items Allen-Bradley for PLC CLX-5000/1756 chassis for PLC √ Ethernet and Ether/IP for IOC communication √ ControlNet for outboard I/O communication √ 1 for FEE Gas Flow; 1 each for FEE, NEH, XRT vacuum For ‘logical’ independence Flex-I/O for I/O points Inexpensive Built-in screw terminals (simple) Mounted vertically in racks with co-located controllers 1 for FEE Gas Flow; 3 for FEE; 1 for each NEH Hutch; 5 for XRT; 1 for FEH VAT VF-2 Fast Shutter between Dump and FEE Bi-directional protection Vendor supplied sensors, shutter, cables

5. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 5 Common Items ‘Cross-over’ Valve Logic The PLC that controls it needs a pressure indication ‘from the other side’ Use two signals: 1/0 => HV; 0/1=>atmos; 0/0 and 1/1 => no power, disconnected cable, etc PLC can resolve permission-to-open logic for any case

6. Steve Lewis SALewis@slac.stanford.edu XTOD Controls FDR 13 March 2008 6 Machine Protection System Each PLC summarizes status of items that can intercept beam; Isolation valves must be OUT Apertures must be IN or OUT MPS gets ‘OK’ if all of above are TRUE (‘and-operation’) Wired to MPS node in NEH hall with 24V pair Signals list: PLC:FEE1:E101 VVPG:DMP1:881FstSht VVPG:FEE1:111FstSht VVPG:FEE1:421KS VVPG:FEE1:451TE VVPG:FEE1:481DI VVPG:FEE1:761HOMS VVPG:FEE1:861HOMS VVPG:FEE1:1721SOMS VVPG:FEE1:1791SOMS VVPG:FEE1:2831SOMS VVPG:FEE1:1831SOMS VVPG:NEH1:131NEHVac VVPG:NEH1:2131NEHVac VVPG:NEH1:1131NEHVac PLC:FEE1:E202 VVPG:FEE1:201GasAtt VVPG:FEE1:211GasDet VVPG:FEE1:221GasDet VVPG:FEE1:231GasDet VVPG:FEE1:241GasDet VVPG:FEE1:251GasAtt VVPG:FEE1:261GasAtt VVPG:FEE1:311GasAtt VVPG:FEE1:341GasAtt VVPG:FEE1:351GasAtt VVPG:FEE1:361GasDet VVPG:FEE1:371GasDet VVPG:FEE1:381GasDet VVPG:FEE1:391GasAtt PLC:NEH1:203 VVPG:NEH1:291NEHVac VVPG:NEH1:2211NEHVac PLC:XRT1:104 VVPG:XRT1:111TnlVac VVPG:XRT1:5251TnlVac VVPG:XRT1:5611TnlVac VVPG:XRT1:5991TnlVac PLC:FEH1:505 VVPG:FEH1:5441FEHVac
