The Manipulation and Characterization of FEL X-ray Beams
September 21, 2010 • Argonne Guest House, Conference Room A
9:00 am — 5:00 pm
Phil Heimann (ALS) and Jerry Hastings (SLAC)
For synchrotron radiation over the past decades, our community has continuously improved the focusing and diffracting of x-rays and as well as the characterization of flux, intensity, focus and bandwidth. However, because of the high intensity per pulse and the ultrafast pulse duration from operating x-ray Free Electron Lasers (FELs), such as LCLS and FLASH, new methods are required. This workshop will cover the presently available techniques to manipulate and characterize FEL x-ray beams. Topics will include splitting and recombining x-ray beams by crystals and mirrors, monochromators, optical coatings, absolute intensity measurements, focus measurements, timing, pulse duration characterization, wavefront evaluation, and other diagnostics. Speakers will describe the present, successful techniques as well as challenges for the future.
