  2. Outline • Use of LCLS Standards • Top-level Diagrams • Details of Hardware and Software • Vacuum not shown • Gauges and Ion pumps are LCLS standard • Turbo-molecular and scroll pumps are XTOD only • Have much in common with K-Spect, Direct Imager • Network Infrastructure not shown • Identical across all of XTOD and XES • Supplied by XES group

  5. Hardware • LCLS (or SPEAR) standard • VME Crate, CPU, Timing (IOC) • Weiner 195 • Motorola MVME-6100 • Micro-Research PMC-EVR 200 • Stepper Motor Control • Hytec Industry Pack 8002/8601 Indexer (VME) • Hytec SMDS-4B Driver • Highland V550 LVDT (VME) Consistent Across LCLS and XTOD

  6. Hardware • XTOD only • Digitizer/Signal Conditioner • ICS-130/121 (VME) • Energy Meter • Ophir PE-10 Laserstar (serial) • Attenuator • Optosigma PAT-001 (serial) • Temperature • Lakeshore 340 (serial)

  7. Software • LCLS standard • Device drivers • Hytec Stepper Motor (VME) • Highland LVDT (VME) • EVR Timing (VME) • Serial • Device-level GUI elements • All other tools and utilities • Archiver • Trend Graph • Save/Restore • Automation Sequencer • Alarm Handling • MATLAB Consistent Across LCLS and XTOD

  8. Software • XTOD Only • ICS Digitizer/Signal Conditioner • Vendor: VxWorks driver and support library • XTOD/XES: EPICS ‘device support’ • Automation Sequences • Waveform Processing • In IOC • MATLAB • Attenuator and Lakeshore Temperature Controller • Serial protocol description (using LCLS template) “Interesting” part

  9. Costs and Effort • All controllers, cables, racks, and auxiliary equipment are itemized • Effort for unit testing and commissioning included in overall accounting Hardware Cost = $35K
