Radiation Safety Analysis for the Experimental Hutches at the Linac Coherent Light Source at SLAC

PDF Version Also Available for Download.

Description

The LCLS, the world's first x-ray free electron laser, will be constructed at the Stanford Linear Accelerator Center and is expected to be completed in 2009. A two-mirror system will be used in order to reduce background radiation in near and far experimental hutches. This paper describes the layout of the two-mirror system and also reports on the shielding requirements for the experimental hutches. Two beam loss scenarios for radiation sources are discussed: losses from the high energy electron beam hitting beam components and x-rays produced in the 130 m long undulator and scattered on x-ray mirrors. The FLUKA Monte-Carlo ... continued below

Two beam loss scenarios for radiation sources are discussed: losses from the high energy electron beam hitting beam components and x-rays produced in the 130 m long undulator and scattered on x-ray mirrors. The FLUKA Monte-Carlo particle transport code was used for the shielding design and for the determination of the radiation levels around the experimental hutches.
