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
