Radiation damage of polycrystalline diamond exposed to 62 MeV protons

Radiation damage of polycrystalline diamond exposed to 62 MeV protons

We irradiated two diamond detectors with 62 MeV energy proton beam up to an integrated fluence of about 21015 protons/cm2 at INFN-LNS in Catania (Italy). The detectors were made of two high purity poly-crystal diamond sensors. The electric contacts of the two diamond sensors were from different sour...

Zusammenfassung:We irradiated two diamond detectors with 62 MeV energy proton beam up to an integrated fluence of about 21015 protons/cm2 at INFN-LNS in Catania (Italy). The detectors were made of two high purity poly-crystal diamond sensors. The electric contacts of the two diamond sensors were from different sources and made with different techniques: a proprietary DLC/Pt/Au electric contact and our own novel UV Laser technique. We collected 120 GeV and 62 MeV proton beam data, before and after irradiation, respectively, to extract the radiation damage constant of one poly-crystal diamond sensor by using single crystal diamond detector response as reference.
