【 摘 要 】

Calculations of the dose suffered by the low Z solids, Li, Be, B, B{sub 4}C, BeO and C at various points along the LCLS beamline as a function of FEL photon energy are presented. Specific column densities of attenuator gases necessary to control the dose to C are calculated for assumed damage thresholds of 0.1 eV/atom and 0.01 eV/atom.
