Two-arm semiconductor spectrometer for charged particles for the investigation of absorption by nuclei of stopped negative pions
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.
