XTOD Scope
Transport the x-ray beam, in vacuum, to all the
experimental stations
Condition the x-ray beam, with attenuators and apertures
Analyze the x-ray beam, with sophisticated diagnostics

XES Scope
The X-Ray Endstation Systems group provides the
infrastructure required for experimenters to make best
scientific use of the LCLS radiation safely

Laser Group Scope
The Laser group coordinates laser design and acquisition
throughout the LCLS. Lasers will be used in the electron
gun and x-ray experimental areas, and also possibly for
accelerator diagnostics and alignment.

Building up the X-Ray Systems
XTOD group has about 20 people now
XES has 1 person and 2 openings
LUSI has 5 openings now, more soon
2 other x-ray related hires at LCLS, 1 opening

LCLS CE costs are expected to be high
May will need to cut some scope
Need to prioritize possible cuts

Possible Scope Reductions
Eliminate flipper mirrors (~$1M)
Reduce length of x-ray transport tunnel by 10%
(20m, ~$0.5M)

Effects of reductions
No flipper mirrors: beamline shared in FEH
Shorter tunnel: side beams closer to each other by 10%
(1.8m vs 2m)
