用 5台带有慢化剂 (聚乙烯 )的BF3正比计数管中子探测器测量中子通量和剂量当量 .4台置于HL_1M装置的四周 ,分别测量了在氘等离子体条件下 ,因欧姆加热和波加热产生的热核聚变中子产额、中子通量和剂量 ,以及氢等离子体条件下因高能x射线引起的光致核反应而产生的光致中子 .另一台流动于其他 6个观察点 ,主要监测中子剂量当量 .在D_D聚变条件下 ,实测中子产额与计算值作比较 ,两者在数量级上大体一致 .中子辐射剂量当量远低于国家和部颁标准 ,更低于国际防护委员会推荐的中子辐射允许剂量当量最大值 .
Neutron flux and dose equivalent were measured using five BF3 proportional counter neutron detectors with moderator (polyethylene). Four sets were placed on the periphery of the HL-1M apparatus and were measured in deuterium plasma Neutron fusion neutron yields due to ohmic heating and wave heating, neutron flux and dose, and photoinduced neutrons due to photonuclear reactions due to high-energy x-rays under hydrogen plasma conditions. The other six observation points, the main monitoring neutron dose equivalent in the D_D fusion conditions, the measured neutron yield and calculated value for comparison, both in the same order of magnitude on the order of magnitude neutron radiation dose far lower than the national and ministerial Standard, lower than the maximum allowable dose equivalent of neutron radiation recommended by the Commission for International Protection.
