During the XFEL prototype module tests on the module test stand at DESY RF power measurement anomaly on the high order mode (HOM) couplers on the cavity operating frequency was detected and investigated. HOM coupler multipacting, predicted by the analythical simulations, was found to be the source of the anomalous signal peak. TESLA type SRF cavity HOM coupler multipacting simulations and observations are presented, compared and discussed.
