摘要

对用于放射性次级束测量的大面积双维位置灵敏探测器（PSD）的性能进行了测试。通过选择实验中电子线路的脉冲成形时间

并改进数据处理方法

即主放大器的成形时间常数要大于6 μs

而位置路的时间常数约为 0 .5— 1μs

且在位置公式中使用能量信号作为分母

测试得到了较好的位置分辨和能量分辨及线性。结果表明

这一类型的PSD探测器可以用于低能放射性束流的测量

Abstract

A two-dimensional position sensitive detector (PSD) which will be used in the measurement of the radioactive ion beam has been tested. By carefully selecting the pulse shaping time contants in the electronics and improving the method of data analysis; i.e. as the main amplifier’s shaping time was more than 6μs and position signal’s shaping time was 0.5—1μs

and used the energy signal as the denominator in the formula of position

better position resolution

energy resolution and position linearity have been obtained. The result shows that these type detectors can be used in the measurement of low energy radioactive ion beam.
