4. Observation of 3rd Harmonic, 1st Undulator
At the last possible shift before the 3 week shutdown, Joe Frisch and Rick Iverson got some good data showing the effect on the 3rd harmonic of the undulator radiation of the Yttrium K edge in the YAG screen that Henrik Loos set up with. Analysis has just started but I I have attached some plots that thought you might be interested in.
Picture 1 is the overall picture, taken with 100 camera shots added together and the background subtracted. The yellow stripe is the dipole radiation, which actually goes down but in this series of picture is inverted. You can see the aperture due to the vacuum chamber as well as the general shape of the xray radiation from the
U25 segment.

5. 21 Undulators Installed
Enough to saturate at 1.5 A

10. Must get ready for experiment program
Issues for the Summer
Must get ready for experiment program
John Arthur leading this effort
Must get XR diagnostics and AMO installed
Geoff Pile (ANL) spending the summer with us
Must Commission XR systems in near hall
Lining up reinforcements for this too.

11. Commission Front End XR Diagnostics 1 May Get AMO on the floor in July
Summer Look-Ahead
Re-start linac 1 April
Additional testing time for Personnel Protection
Re-commission undulator e-beam systems
Look for gain at 13.6 GeV
Commission Front End XR Diagnostics 1 May
Continue installation of Front End (mirrors, etc)
Get AMO on the floor in July
Commission AMO in August
Users in September

12. PROJECT SAFETY EXPERIENCE Through February 2009
DART Rate
Total Project Hours
2.14 M Hours worked
DART Rate 1.03
SubContractors
594 K Hours worked
DART Rate 3.03 (9 Incidents)
TRC Rate (3 Incidents)
LCLS Collaboration
1,546 K Hours worked
DART Rate 0.26 (2 Incidents)
Injury rates based on 200 K hours (100 man years) of effort. DOE/SC Goal is a Reportable Case (TRC) rate of < 0.25 and a Days Away, Restricted, or Transferred (DART) rate < per 100 FTEs.

13. From AMO to End of Project
Build Far Hall Hutches
Get ready for accelerated LUSI activities
Execute Space Renovation
Detect X-Rays in Far Hall
