用于Q3D磁谱仪的重离子半焦面探测器已安装、调试完毕,并用72MeV的~(16)O弹性散射离子在磁谱仪上作了初步在束检验。重离子焦面探测器的结构示意图如图1所示。入射窗为mylar膜;两个正比计数管
The heavy ion semi-focal detector used in the Q3D magnetic spectrometer has been installed and commissioned. The initial beam test was performed on the magnetic spectrometer with ~ (16) O elastic scattering ions of 72 MeV. Heavy ion focal plane detector structure diagram shown in Figure 1. The entrance window is a mylar membrane; two proportional counters
