描述了一种双维位置灵敏CsI(Tl)探测器的结构及其读出系统,用中能次级束研究其能损与光输出关系。使用Bp+(△E-TOF)方法鉴别次级束,刻度了CsI(Tl)探测器位置信号的线性,并用其光输出与入射粒子的A、Z关系刻度其能量。结果表明,CsI(Tl)探测器输出信号的ADC读出与QDC读出(即其光输出)有很好的线性关系。
In this paper, we describe the structure and readout system of a two-dimension positional sensitive CsI(Tl) detector, and investigates the relation between energy lose and light output of the CsI(Tl) detector with secondary beams in intermediate energy. Bp+(△E-TOF) method was used to distinguish the secondary beam. Linearity of the position signals of the CsI(Tl) was corrected. Energy signals from the CsI(Tl) detector were calibrated using the relationship of the Z, A and the light output response of the incident particles. A good linear relation was found between the ADC output signals and the QDC(light) output signals of the CsI(Tl) detector.
