LCLS Undulator Diagnostics and Commissioning Workshop

University of California at Los Angeles (UCLA)

Knudsen Hall and Faculty Center

January 19-20, 2004

A two-day workshop was held at UCLA to discuss aspects of commissioning the undulator and FEL portion of the LCLS. The scope of the workshop includes electron beam diagnostics upstream as well as along and after the undulator, x-ray diagnostics along and downstream of the undulator, beam-based alignment, and commissioning goals. The discussion included how the scope of start-to-end simulations can be expanded to include simulations of diagnostics devices.

UCLA Point of Contact: Sven Reiche, UCLA +1-310-206-4540
Administration: Melinda Laraneta, UCLA +1-310-206-2499
