Determine 3. Temperature dependence from the Power resolution. The outcomes were calculated from the height width (full width at half utmost—FWHM) on the IBIC spectra recorded about the unirradiated detector region employing two MeV protons for a probing beam.
The demand collection effectiveness (CCE) inside the ruined spots was monitored using 2 MeV protons and also the ion beam induced charge (IBIC) approach, indicating that the CCE decreases with raising temperature. This lowering craze saturates within the temperature range of roughly 660 K, after which CCE recovery is noticed. These results advise which the radiation hardness of diamond detectors deteriorates at elevated temperatures, despite the annealing results which might be also noticed. It ought to be noted that the diamond detector investigated herein retained its very good spectroscopic properties even at an Procedure temperature of 725 K (≈two% for two MeV protons).
