基于LabVIEW设计的RPC-Gd热中子探测器测试系统

在WinXP系统下,基于LabVIEW开发了RPC-Gd热中子探测器的性能测试系统。结合LabVIEW图形显示能力和仿真仪器面板功能,通过调用外部动态链接库机制,封装CAMAC的I/O接口命令为功能函数子VI系列,以此将各电子学插件编译为功能模块。根据不同实验的要求可对功能模块进行灵活选择和设置。测试系统具有开放性、可移植性,使用界面友好简易。

Study of the RPC-Gd as thermal neutron detector

The BESⅢ ·RPC with Gd coating as thermal neutron detector was designed and constructed. Three prototypes were built with different techniques of producing the gadolinium converter. The performance of the cosmic ray test, the signal and the radiation spectrum were discussed in this paper. Lastly, the efficiency of one prototype with the best performance for detecting the thermal neutron was tested as 8.7%.
