PETP固体径迹探测器的性能研究

Abstract

报道了聚乙烯对苯二酸酯（简称PETP）固体核径迹探测器时裂变碎片记录性能的实验研究．在改变温度、蚀刻时间和蚀刻液浓度等条件下测量了裂变碎片径迹平均直径的变化。实验结果表明：蚀刻液温度的变化对裂变碎片径迹的影响最大；而浓度和蚀刻时间的影响不大.同时用低能16O重离子辐照PETP探测器，并得到了它的标定曲线．The characteristics of polyethyleneterephthalate (PETP) solid state nuclear track detector on registering fission fragment tracks are studied. The variations of average diameter of fission fragment tracks with etching temperature, etching time and etchant concentration were measured. It is shown that among the three factors the influence of etching temperature on fission fragment tracks is the greatest. The PETP detectors were irradiated with low energy 16O heavy ions and the calibration curve was obtained.国家自然科学基金!19405006;;中国科学院“八·五”重大项
