Long-term exposure of a polycrystalline diamond detector irradiated by 62 MeV/nucleon carbon beams

The present work reports on a long-term irradiation test performed on a 0.3-mm thick polycrystalline diamond detector prototype. The device, biased at 300 V, was continuously irradiated for about 60 h by using a 12C beam at 62 MeV/nucl. at the LNS-INFN Cyclotron facility in Catania. An ionization ch...

Description
Summary:The present work reports on a long-term irradiation test performed on a 0.3-mm thick polycrystalline diamond detector prototype. The device, biased at 300 V, was continuously irradiated for about 60 h by using a 12C beam at 62 MeV/nucl. at the LNS-INFN Cyclotron facility in Catania. An ionization chamber, calibrated using a single crystal diamond detector, was used to evaluate the total absorbed dose in the diamond detector under study. Data analysis carried out on recorded oscilloscope waveforms shows no significant variation of the signal properties in terms of amplitude, slope and charge after exposure to an integrated flux of 6.2⋅ 1013 ions/cm2. The results indicate that a polycrystalline diamond detector can be used for calibrating intensity monitors at the future superconducting fragment separator Super-FRS at FAIR (Darmstadt). •No change observed in the signal proprieties of an irradiated pcCVD diamond material•Diamond detectors as precise intensity monitors with heavy ion beams•Survival of a pcCVD diamond detector after long-term beam current calibrations
