Abstract

The authors examine the radiation field produced in the vicinity of the main beam dump of the FERMI free-electron laser under the impact of a 1.4-GeV electron beam. Electromagnetic and neutron dose rates are calculated with the Fluka Monte Carlo code and compared with ionisation chamber and superheated drop detector measurements in various positions around the dump. Experimental data and simulation results are in good agreement with a maximum deviation of 25 % in a single location.
