Abstract

The planned Linac Coherent Light Source (LCLS) will operate at a rate of 120 x-ray pulses per second. Therefore, when considering effects leading to the damage to its optics, one has to be concerned not only with a possible damage within one pulse, but also with effects accumulating during many pulses. Two of such effects: a thermal fatigue, and the intensity-dependent radiation damage, have been identified and analyzed in this paper. Constraints on the admissible fluence per pulse have been derived and ways for decreasing the impact of the multi-pulse effects have been suggested.
