【摘要】 经改进后的轻重离子焦面探测器系统（长５００ｍｍ）已通过束流检验并用于核物理实验中。在串列加速器上，以６６ＭｅＶ￣（１２）Ｃ束流，测得该系统的位置分辨为１．３ｍｍ；ΔＥ探测器的能量分辨约为６％；剩余能量Ｅ探测器的能量分辨约为７％；总能量分辨约为３．４％。另外还进行了粒子鉴别试验。更多还原

【Abstract】 The improvement of the focal-plane detector system(500 mm long)for light heavy ions ismainly described.The improved light heavy ions focal-plane detector system is tested with beamand used in nuclear physics experiment.The measured results at tandem accelerator with 66 MeV￣(12)C beam are as follows:position resolution is 1.3 mm;the energy resolution of ΔE detector isabout 6%;the energy resolution of the E detector is about 7%;the total energy resolution isabout 3.4%。The experiment of particle discrimination is performed.更多还原
