Abstract

For the high multiplicity events occuring in relativistic nuclear collisions an electronic 4τ detector with particle identification has been built. It consists of 815 ΔE - E telescopes and 176 TOF telescopes covering 97% of 4π. Very good particle identification has been obtained for hydrogen and helium isotopes and also π+ have been detected with high efficiency.

    The detectors used in the pionic-fusion experiments are shown schematically in Fig. 1. The Plastic Ball (PB) [6] and the Inner Shell (IS) [7] are designed to detect a neutral pion via two-photon decay. The HI detector array readout (see scheme in Fig. 4) was configured with standard CAMAC and NIM electronics.
