【摘要】 本文介绍一个多条闪烁描迹仪和一个小型描迹仪在线系统。描迹仪目前为4×4的正交闪烁计数器阵列。闪烁计数器由50×4×1cm³的NE-104塑料闪烁条和国产GDB-50L光电倍增管组成。我们编写了一个适用于描迹仪性能测量的在线程序。将描迹仪读出系统与PDP-11/03计算机相连接,进行了在线实验。测得如下实验结果:描迹仪各单元探测效率在96.5％—99.5％之间;将Ru¹⁰⁶放射源放在不同位置,可以以直方图的形式迅速而直观地在打印机上显示出相应的计数分布;还测量了宇宙线的流强及天顶角分布。测量结果合理。整个系统工作稳定可靠,可以用于高能物理实验。更多还原

【Abstract】 In this paper, a multi-strip scintillation counter hodoseope and a small on-line system are described.The hodoscope is a 4×4 array of scintillation strip counter, each of which consists of a plastic scintillation strip of type NB104 with the dimension of 50×4×1cm³ and a Photomultiplier of type GDB-50L. An on-line program for hodoscope property test has been compiled. The hodoscope read-out system is linked with PDP-11/03 computer and with them some on-line experiments have been done.The experimental results are as follows. The efficiency of each cell of the hodoscope is between 96.5% and 99.5%. The counting distribution caused by a radiative source Ru¹⁰⁶ put at various locations can be displayed as a histogram directly and promptly on a printer. The intensity of cosmic ray fluxes and its distribution versus azimuthal angle has been measured. All these results are reasonable. The performances of this system are well and stable and it can be used in some experiments of high energy physics.更多还原
