LCLS Total EnergyFinal Design Review

outline
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

“Interesting” part

costs and effort
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
