Abstract

This manuscript presents a first study of the contamination observed on some of the x-ray mirrors for the Linac Coherent Light Source (LCLS) free-electron laser, the implications to the mirror lifetime properties and an evaluation of candidate techniques towards successful recovery of these B₄C- and SiC-coated mirrors. Initial experimental results and plans for upcoming mirror recovery experiments are discussed. A summary of experimentally determined FEL damage thresholds of B4C and SiC materials is also given, and their wavelength dependence is discussed.
