摘　　要：本文描述一个大量程粒子望远镜.它由一个平行板雪崩探测器(PPAC),一个电离室(IC)及一个光迭层探测器(phoswich)组合而成.它适合于很宽能区内轻粒子和重碎片的测量.该探测器在近代物理研究所1.7米迴旋加速器上用96MeV^(16)O+^(51)V反应中30°方向上的产物进行了调试,测量结果表明,电离室和Phoswich构成的望远镜对电荷数Z>2的粒子给出了极好的分辨(_8^(16)O的Z分辨达到5％);Phoswich本身对H、d、t、α等轻粒子也给出了相当好的分辨.A large range combined detector is described.It is composed of a parallel plate avalanche counter(PPAC),anionization chamber(IC)and a phoswich.It was tested with the fragments at 30° produced by the reaction 96MeV ^(16)O+^(51)V on the 1.7m cyclotron in IMP.The heavy-fragment telescope composed of the(IC)and the phoswich gives excellent charge resolution ΔZ/Z≈5%(FWHM)for oxygen,and the phoswich itself gives good particle resolution for the light particles such as p,d,t,α etc.
