采用ZnS(Ag)闪烁计数器,经标准中子源刻度校正后,测量HL-1(中国环流器一号)聚变装置的中子演化和中子产额;同时用活化箔法(115In)和原子核乳胶法测量中子产额。在真空室充氘和电子回旋共振加热(ECRH)时,3种方法同时测量,确证HL-1每放电1次发射中子数平均为(3.41±0.50)×1010。得到欧姆加热、ECRH、改进约束放电(IOC)和弹丸注入等放电实验中的中子演化。在分子束注入和偏压电极(EPP)放电实验中,产生中子较少或很少。观察部分放电方式产生的中子产额N和硬X射线产额HX间有线性关系N=aHX-b,其中,a和b是与装置运行方式有关的常数。
The neutron evolution and neutron yield of the HL-1 fusion device were measured with a ZnS (Ag) scintillation counter calibrated with a standard neutron source. At the same time, both the activated foil method (115In) and nuclei Latex method to measure neutron yield. When the vacuum chamber was filled with deuterium and electron cyclotron resonance heating (ECRH), the three methods were simultaneously measured and confirmed that the average number of neutron emission once per discharge of HL-1 was (3.41 ± 0.50) × 1010. The neutron evolution in ohmic heating, ECRH, modified IOC and projectile injection were obtained. In molecular beam injection and bias electrode (EPP) discharge experiments, fewer or fewer neutrons were produced. Observed part of the discharge mode of neutron yield N and hard X-ray yield HX linear relationship between N = aHX-b, where, a and b are related to the mode of operation of the device constant.
