The latest large-scale research facility of the Paul Scherrer Institute, the x-ray free-electron laser SwissFEL, is installed in a 740 m long building. The facility accelerates electrons to a maximal energy of 5.8 GeV with repetition rates up to 100 Hz. The building is integrated in a regional recreation area with shielding of the accelerator vault dimensioned to tolerate temporary beam losses. An online dose monitoring system capable of shutting down SwissFEL ensures compliance with legal requirements. The studies present an overview of the evaluation of calibration factors for this system and results of dedicated benchmark measurements, carried out to verify underlying assumptions and simplifications.
