AB - LCLS-II XFEL facility at the SLAC National Accelerator Laboratory will accelerate CW beams of up to 300 uA to 4 GeV using superconducting radio frequency cavities. Before installation, fully assembled cryomodules will be tested at Fermilab and Jefferson Lab. Besides the basic measurements of cavity gradients and cryogenic heat loads, radiation and dark current levels will be recorded. The latter parameters need to be limited to ensure the safety of the machine and the lifetime of radio-sensitive components installed near the cavities. In this paper we describe the simulation studies being done in preparation of tests, where expected radiation measurements in the different detectors are correlated with field emission and with dark currents in Faraday cups at each end of the cryomodule. This work includes simulations using a detailed model of the cryomodules and detectors, where field emission data generated with Track3P is parsed to the FLUKA radiation transport code.
