  2. Overview • 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 are XTOD only • Have much in common with K-Spect, Total Energy • 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 • Hytec SMDS-4B Driver • Ladder Position • Heidenhain ROQ-425 Absolute Encoder • Kramert ECM-550/F Readout Consistent Across LCLS and XTOD

  6. Hardware • XTOD only • Filter Wheel • Finger Lakes Instrumentation CFW-1, 2 • RS-232 • CCD Camera • Princeton Instruments Cascade 512B • PCI • Dell 1950 computer (Linux) • Also used by XES (IOC)

  7. Software • LCLS standard • Device drivers • Hytec Stepper Motor (VME) • Kramert Encoder (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 Future: RTEMS (can support timing) • XTOD Only • Cascade 512B • Vendor: Linux driver and support library • XTOD: EPICS ‘device support’ • Automation Sequences • Image Processing • In IOC • MATLAB • Filter Wheel • 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 = $33K
