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
