Typical energy spectrum <strong>of</strong> <strong>Pr</strong>:<strong>Lu</strong>AG excited <strong>by</strong> 241Am alpha-ray source at room temperature.<br />
5.5MeV peak is<br />
clearly detected<br />
• 5.5MeV alpha-ray peak is clearly detected <strong>by</strong> using <strong>Pr</strong>:<strong>Lu</strong>AG and InGaN-PD<br />
• The energy resolution was around 29%<br />
• This result indicates a possibility that combination <strong>of</strong> <strong>Pr</strong>:<strong>Lu</strong>AG scintillator and<br />
InGaN-PD can be applied to radiation detection application.
