摘要

在HIRFL通用散射室的终端调试时完成了0°附近Pilot U塑闪墙的性能测量

给出了位置分辨为Δx=3cm

时间分辨为600ps

并能分辨出Z≤6的几种主要粒子

测得100×5×1cm

的Pilot U有效光速为16.37cm/ns

有效衰减长度为92.4cm

并解决了同一条塑闪在0°附近的粒子多击问题。

Abstract

A light particle detection unit for the large spherical scattering chamber of HIRFL using plastic wall of 100×5×1cm3 and 100×10×1cm3 Pilot U plastic scintillators is described. Each module provided information on particle impact position

time of flight

and atomic number Z

which was studied on line with heavy-ion beam. The resolutions of position and time are 3cm and 600 ps respectively

but the charge identification is poor. The effective speed of light ceff in 100×5×1cm3 Pilot U is 16.37cm/ns and the length of light attenuation λeff is 92.4 cm.
