The aim of the WEBEXPIR experiment was to check for any LBE surface distortion or enhanced evaporation as a result of surface heating with a 7 MeV electron beam in conditions representative of the MYRRHA/XT-ADS spallation target. Various tests have been carried out at electron beam currents of up to 10 mA, which corresponds to 40 times the nominal beam current necessary to reproduce surface heating in relevant conditions. No signiﬁcant shockwave effects or enhanced LBE evaporation were detected. As a ﬁrst preliminary conclusion it can be stated that the WEBEXPIR free surface ﬂow was not disturbed by the interaction with the electron beam and that the vacuum conditions stay well within design specifications of the MYRRHA/XT-ADS application.
