Cost estimation of an energy recovery Linac light source

A cost estimation model for scaling energy-recovery linacs (ERLs) has been developed for estimating the impact of system-level design choices in scaling superconducting accelerator facilities. The model consists of a number of modules which develop subsystem costs and derive as a budgetary criterion. The model does not include design engineering or development costs. Presented in the paper is the relative sensitivity of designs to the accelerators and the refrigerators while allowing the accelerating field to optimize
