Abstract

A two-arm semiconductor spectrometer for the detection of secondary charged particles, such as p, d, t, ³He, ⁴He and of their correlations in the process of stopped pion absorption by nuclei is described. The spectrometer consists of two telescopes of Si-detectors with a sensitive surface of 800 mm², two semiconductor detectors as monitors and the “live” target, a silicon surface barrier detector. The number of semiconductor detectors is 19.

A technique for pion stop selection in thin targets is described.

The problem of particle identification and of measurements of their energy with the help of a multicrystal semiconductor telescope is discussed. The technique provides an absolute normalization of spectra. The “alive” target helps to obtain more information on the process of pion absorption by Si-nuclei.

用于研究被停止的负介子的核吸收的带电粒子的双臂半导体光谱仪

描述了一种用于探测二次带电粒子(如p、d、t、3He、4He)及其在原子核停止介子吸收过程中的相互关系的双臂半导体光谱仪。该光谱仪由两个硅探测器望远镜组成，其敏感表面为800平方毫米，两个半导体探测器作为监视器和“活”目标，一个硅表面势垒探测器。半导体探测器的数量为19个。介绍了一种在薄靶中选择介子停止点的技术。讨论了利用多晶半导体望远镜进行粒子识别和粒子能量测量的问题。该技术提供了光谱的绝对归一化。“活的”靶有助于获得更多关于si核吸收介子过程的信息。
