介绍了HL-2A型中子产额测量装置的研制，该装置包括235U裂变室和BF3、3He正比计数器。推导了辐射探测信号放大系统的等效噪声公式，以指导信号放大系统的研制。然后利用252Cf中子源对所有探测器进行了现场标定。分析了HL-2A中性束加热过程中的中子产额。这些结果表明，所研制的中子通量诊断系统可以获得HL-2A托卡马克各种实验条件下的中子产额结果，并能提供有关中子产额的信息。
This research presents the development of HL-2A neutron yield measurement which includes 235U fission chamber and BF3 and 3He proportional counters. Equivalent noise formula of the radiation detection signal amplification system was derived to guide the development of the signal amplification system. Then all detectors were calibrated in situ by using the 252Cf neutron source. The neutron yield of the HL-2A during neutral beam heating was analyzed. These results indicate that the developed neutron flux diagnostic system can obtain neutron yield results under various experimental conditions of the HL-2A Tokamak, and can provide information on neutron yield.
