用上海硅酸盐所提供的φ76mm×100mm BGO晶体制作γ闪烁探测器、用来探测???离子核反应中放出的10-100 MeV的γ射线,该探测器对~?Cs的0.661 MeV γ射线的?????14.2%。在加速器上用若干(p,γ)反应产生的单能光子测试探测器的能量响应,通过细致的数?拟合得到该探测器在20 MeV以下能区的能量响应和全能峰能量分辨率。对17.65 MeVγ射线。探测器的能量分辨率为4.1%。
Γ-scintillation detector made of φ76mm × 100mm BGO crystal provided by Shanghai Silicate was used to detect the γ-ray of 10-100 MeV emitted in the ion-nuclear reaction. The detector yielded 0.661 MeV γ-ray The ?????? 14.2%. The energetic response and the all-energy peak energy resolution of the detector in the energy region below 20 MeV are obtained by the exponential fitting of the energy response of the detector with a single photon generated by several (p, γ) reactions at the accelerator. For 17.65 MeV gamma rays. The energy resolution of the detector is 4.1%.
