ｄ－Ｔ聚变反应产生的１６７ＭｅＶγ射线很弱，必须从很强的γ、中于混合场中筛选出来，故要求探测系统有高的信噪比，快的时间响应和宽的动态范围。利用高能γ与介质相互作用的康普顿效应及其定量对应关系，由扇形聚焦磁场一次偏转，用ＣＯ２气体切连科夫探测器（ＧＣＤ）探测电子束，或由扇形聚焦磁场（ＳＣＤ）二次偏转，用有机玻璃切连科夫探测器测电子束。仔细考虑了探测装置的辐射屏蔽和探测系统的电磁屏蔽。分别在“闪光－１”装置、ＤＨＪ－２５回旋加速器和２ＭＶ直线加速器上对探测装置进行了模拟检验实验和标定实验。在实际测试中，首次获得了纳秒级ｄ－Ｔ聚变反应产生的１６７ＭｅＶγ波形。
The 167MeV gamma ray produced by the d-T fusion reaction is very weak and must be screened out from a very strong gamma-ray in a mixed field. Therefore, the detection system needs a high signal-to-noise ratio, a fast time response and a wide dynamic range. Using the Compton effect of the interaction of high energy γ with the medium and its quantitative correspondence, the magnetic field of the fan-shaped focusing field is deflected once, and the electron beam is detected by the CO2 gas-clog detector (GCD) or by the sector-shaped focusing magnetic field The second deflection, with the Perspex Cherenkov detector electron beam. Careful consideration of the radiation shielding of the detection device and the electromagnetic shielding of the detection system. The simulation test and calibration experiment were carried out on the detector at “Flash-1” device, DHJ-25 cyclotron and 2MV linear accelerator, respectively. In the actual test, the 167 MeVγ waveform produced by the nanosecond d-T fusion reaction was obtained for the first time.
