- 論文の詳細を見る
Flux monitoring in the specimen chamber of FGRL was carried out by directly and continuously reading with a γ-ray spectrometer the content of <SUP>16</SUP>N in the primary cooling water produced by <SUP>16</SUP>O(n, p)<SUP>16</SUP>N reaction within the cooling jacket of FGRL. <SUP>16</SUP>N generation is not influenced by γ-ray build-up in the reactor nor by the temperature in the specimen chamber. The detector can be simply set outside the pipe through which the cooling water flows, because the high energy γ-rays (6.13MeV) emitted during the <SUP>16</SUP>N decay easily penetrate the pipe wall.
