【Abstract】 The updated structure and specifications of the high performance detector system of TR4 at HIRFL are described. The system consists of Si multi-unit telescopes, IC + PSD + SPD + CsI(T1) logarithmic density telescopes, projectile-like fragment TOF spectroscopes, 3 × 3 and 6 × 6 CsI(T1) scintillator arrays and Si + CsI(T1) light particle telescopes. The Z/△Z ￣ 50 and BE/E ￣ 0.3% for St telescopes, Z/ △Z ￣ 44.5 and △x ￣ 1.7mm for logarithmic density telescope,A/△A ￣ 86, Z/△Z ￣48, △E/E ￣ 0.78 % and △t ￣ 286ps for projectile-like fragment TOF spectroscope focusing with elliptic surface mirror are obtained.更多还原
