摘要
We present the characteristics of the segmented BaF2 calorimeter TAPS for the measurement of charged pions and protons. The method of particle identification exploits the relation between the kinetic energy of a particle, its mass and the time-of-flight required to reach the detector. The detection efficiency is calculated using GEANT-GCALOR simulations. The analysis method is applied in the reaction 40Ar+natCa at 0.8AGeV. The simultaneous detection of charged pions and protons can be used to search for correlated pairs signalling the de-excitation of the Δ(1232) resonance.
