Commissioning of the CMCF 08ID-1 Beamline

Light in the Optical Hutch September 2005 Light at the entrance to the white beam slits (42 m). The rectangular “glow” comes from the light produced by the in-vacuum small-gap undulator. The gap was at 8.0 mm and the ring current 10 mA. The screen is a CVD- deposited diamond foil doped with nitrogen atoms. Small round spot from a visible BM light. After the FE valve was opened! November 2005 Monochromatic light, just downstream of the DCM (45 m). 18 mm Gap = 12 mm (10 keV, 3 rd harmonic) Current = 90mA

First diffraction patter. March 18, E=9.31 keV, d=260 mm, exposure 3s.

End-station

Issues Not sufficient, not complete or wrong info from vendors (motors, gearboxes) Poor design of some components, no reference switch (crystal bender, yaw) Malfunction equipment equipment that cannot be tested without the light (SESO XBPM, BPM) Installation of optics without functional control system Implementing physical units Problems with saving the “final” motors’ parameters Not implemented feedbacks from encoders Noise from “high current” motors Lack of man power to finish “control” of the end-station before the first light (high current motor drivers)
