Description
The possibilities of using a monitor system 1 based on semiconductor Si detectors (SCD) for reconstructing the spectra of short-range charged particles in experiments to study the mechanisms of stopped negative pion absorption by nuclei 2 are considered.
The method is based on the possibility of measuring the stopping depth of a pion in a thick ( 100 µg/cm2) target by the amount of energy loss in monitor Si detectors. The characteristics of the system are considered and the method of their measurement is proposed. Various methods of reconstructing the spectra of short-range particles from thick targets are analyzed and their applicability in both inclusive and correlation measurements with the registration of pairs of charged particles for coincidence is demonstrated.
The use of this approach makes it possible to increase the efficiency of research by combining the maximum statistical data security with the advantages of experiments on thin (~20 µg/cm2) targets.
