概要
- 論文の詳細を見る
Photo-neutron emission in H<SUB>2</SUB> and He discharges was observed in the initial ohmic heating experiments of the Heliotron-E. Typical total neutron yield was 10<SUP>9</SUP> neutrons per pulse under high level of runaway electrons ( ?? 10 MeV). Neutron flux was localized near the limiters. Energy spectrum of neutrons was continuous up to about 2 MeV. The radioactive nuclides in the limiters and the vacuum chamber irradiated by runaway electrons showed that <SUP>58</SUP>Ni (r, n) <SUP>57</SUP>Ni and <SUP>53</SUP>Cr (r, n) <SUP>51</SUP>Cr reactions had occurred, proving that the photodisintegration process was the source of neutron flux.
