Au-Si面垒型带电粒子望远镜的研制

Development of Au-Si Surface-barrier Charged-particle Telescope

介绍了厚度为350μm、有效面积为530mm2的ΔE和厚度为700μm、有效面积为1380mm2E探测器所组成的全耗尽Au—Si面垒型带电粒子望远镜的制备工艺、测试结果(Thc-c/源8.78MeV的能量分辨率ΔE探测器为0.8%、E探测器分辨为1.2%)和该探测器的主要用途。

The Au-silicon surface-barrier charged-particle telescope detect system . The mean fabrication process of The total depleted Au-silicon surface barrier charged particles telescope detect system is briefly described in the paper , The system is comprised of △E-E. the△E detector having sensitive layer of 350 /ma and active area of 453 mm2; the E detector having sensitive layer of 700μm and active area of 1385 mm2. energy resolution of FHWM=0.8 % for the △E and FHWM=1.2 % for E , for energy loss of Thc-c/ 8.78MeV a-particles have been obtained. The telescope detect system con is used for the measurement of exotic nucleus βdelayed proton.
