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. Includes advanced x-ray detector R&D.

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.

LUSI Project Scope
LCLS Ultrafast Science Instruments is a distinct DOE project closely coordinated with LCLS. It will build 4 science instruments which will occupy LCLS x-ray hutches. This will enable work in three of the LCLS Science Thrust Areas: X-ray pump-probe dynamics, Coherent x-ray imaging, and X-ray photon correlation spectroscopy. The project is ramping up, with major funding expected in FY2007.

Other Cuts
Some XTOD diagnostics Not needed for commissioning, expect to add as part of operations
Some XES generic detectors Expect that LUSI will provide experiment-specific detectors
XES support for generic computers for experimentsExpect that LUSI will provide experiment-specific computers

Better Beam-Splitting Plan
LCLS and LUSI are working on an updated beam-splitting plan, and a way will be found to implement it
This includes not only splitting of the beam to the FEH, but also splitting into a soft x-ray line and hard x-ray line in the NEH
Will allow quicker changes between experiments
Has become possible as experiment designs are beginning to crystallize
