NEW LCLS Parameters Update

by LCLS Announcement
Currently we are limited to a spectral range down to 750 eV, and we will guarantee this spectral range for experiments scheduled in Spring and Fall 2010. We are also developing operations at lower energies, down to 510 eV. We cannot guarantee it at this time (subject to Radiation Physics review and approval), but we are confident enough to solicit proposals for the Fall 2010.

The minimum pulse duration in standard operation is ~ 70 femtoseconds FWHM. We have developed lower current operation which is now available for users. In this low current moded pulse lengths have been shown to be less than 20 femtoseconds. We believe the pulses are much shorter (for reference see http://www-public.slac.stanford.edu/sciDoc/docMeta.aspx?slacPubNumber=slac-pub-13642) and solicit proposals to measure this.

The maximum repetition rate of the X-ray flashes is expected to be 60 Hz and we are working on moving to 120 Hz.

We will provide updates on additional parameters as they become available.
