In High Energy Physics (HEP) experiments, devices are required to withstand high radiation levels. As a result, detectors and electronics sitting in the inner detector layers must be irradiated to determine their radiation tolerance. To perform these irradiations, CERN built during LS1 a new irradiation facility in the East Area at the Proton Synchrotron (PS) accelerator. At this facility, named IRRAD, a high-intensity 24 GeV/c proton beam is used. During beam steering and irradiation, the intensity and the transverse profile of the proton beam are monitored online. The IRRAD Beam Profile Monitor (BPM) uses a set of four 39-channel pixel detectors constructed using thin foil copper pads positioned on a flex circuit. When protons pass through the copper pads, they induce a measurable current. To measure this current a new data acquisition system was designed as well as a new database and on-line display system. In this work, we present the design and the architecture of the IRRAD BPM system, some results on its performance with the proton beam, as well as its planned upgrades, including its utilization for monitoring irradiations with an intense 300MeV/c positive pion beam at PSI.
