A modified HYPERON spectrometric complex for studying K-meson decays is described. The momentum resolution of the magnetic spectrometers and energy and the coordinate resolutions of the shower hodoscope detectors in the facility are given. The complex reliably identifies beam particles and measures the kinematic parameters of the beam and secondary particles, including gamma quanta. The experiments were performed at the JINR Laboratory of Nuclear Problems.
A lead-glass total-hadron-absorption detector is used to study the space and energy characteristics of hadron showers. A prototype of a calorimeter that has a hodoscopic structure in the longitudinal and transverse directions with a spacing of 10 cm is exposed to a beam of e/sup +/, /mu//sup +/, /pi//sup +/, K/sup +/, and p particles with momenta of 5, 10, and 13 GeV/c. Data are obtained on the energy and coordinate resolutions and on the separation of hadron and electromagnetic showers.
A hodoscopic shower detector is described that contains 256 elements of TF-1 lead glass with dimensions of 85 x 85 x 350 mm and is a part of the Giperon unit. The characteristics and possibilities of the detector are studied using the quasibinary charge-transfer reaction ..pi../sup +/ ..-->.. ..pi../sup 0/ (eta, omega, f) by nuclei at an energy of 10 GeV.
The effect of an active converter on the accuracy of determination of the coordinates of positrons with an energy of 5 GeV in a hodoscopic shower detector is studied. It is shown that the space resolution is improved when the energy release in the active counter, in addition to the ratio of the signal amplitudes of adjacent cells, is taken into account in coordinate calculation.
