Abstract

Research about the proton nuclear reaction is actively achieving on the proton therapy including material development of fusion reactor. The proton induced gamma ray energy(2754, 1386 keV) spectrum of 27Al(p,3p+n)24Na reaction was measured with 100 MeV high energy proton beam. The proton beam in the experiment was derived from 100 MeV proton linear accelerator in the KOMAC. We measured the gamma ray intensity ratio of the decay level from the energy spectrum. The previous results have been compared with the current result. Strength of measured gamma rays will provide very important information though decide high energy gamma radiation detection efficiency.

양성자핵반응에 대한 연구는 현재 핵융합로의 재료 개발을 비롯하여 양성자치료 분야 등을 중심으로 활발하게 이루어지고 있다. 본 연구는 100 MeV 양성자 빔을 이용한 $^{27}Al(p,3p+n)^{24}Na$ 반응을 통하여 발생되는 지발 감마선(2754, 1386 keV) 스펙트럼을 고순도 HPGe 검출기를 이용하여 측정하였다. 실험에 사용되어진 양성자 빔은 양성자가속기연구센터(KOMAC)에 설치되어 있는 100 MeV 양성자선형가속기를 사용하였다. 측정된 감마선은 기존에 알려진 결과들과 비교분석하였다. 측정된 감마선의 강도는 고에너지 감마선 검출효율을 결정하는데 매우 중요한 정도를 제공 할 것으로 생각되어 진다.
