Abstract

Recently, most countries in the world have pursued a denuclearization. So it has been of interest to increase to Nuclear weapon in such as North Korea's continued nuclear test. Pulsed gamma rays produced in the nuclear explosion and the space environment can give the big damage to the electronic device in a very short period of time. To confirm the extent of damage of these electronic devices, pulsed gamma irradiation facility that can occur in nuclear weapon or space environment are required. In this paper, we implemented the pulsed gamma-ray detection module and analyzed output of the irradiation test. We have experimented using an electron beam accelerator research facilities in Pohang Accelerator similar conditions to equip and Nuclear weapon. As a result, we confirmed that the pulsed gamma rays emitted by the gamma radiation and electron beam conversion device. The results of this paper will contribute to improve the reliability and accuracy of studies for utilizing pulsed gamma rays.

전 세계적으로 비핵화를 추구하고 있으나 북한의 계속되는 핵실험 등으로 핵폭에 대한 관심이 지속적으로 증가하고 있다. 핵 폭발 또는 우주환경에서의 발생되는 펄스형 감마선은 매우 짧은 시간동안 고에너지를 전달하기에 전자소자에 큰 피해를 줄 수 있다. 이러한 전자소자의 피해정도를 확인하기 위한 연구를 수행하려면 핵폭 또는 우주환경에서 발생할 수 있는 펄스형 감마선 조사시설이 필요하다. 본 논문에서는 펄스형 감마선 탐지 장치을 개발하고, 감마선 변환장치를 통해 펄스형 감마선을 생성한 후 그 출력을 분석하였다. 핵폭과 유사한 조건을 갖추기 위하여 포항가속기 연구시설의 전자빔가속장치를 이용하여 출력을 실험하였고, 그 결과 감마선 변환장치와 전지빔을 통해 생성한 펄스형 감마선의 방출과 그 출력특성을 확인하였다. 본 논문의 결과는 펄스감마선을 이용해야 하는 연구의 안정성과 정확성을 향상시키는데 기여할 것이다.
