塑料径迹探测器的电荷分辨本领决定于材料本身结构的均匀性、蚀刻温度的稳定性、蚀刻液浓度的一致性等。特别在宇宙线实验中,探测器的面积大、数量多,需要大容积的蚀刻槽,有时还需要分批进行蚀刻。所以,蚀刻温度的控制以及槽内温度的分布对于探测器的电荷分辨本领有着重要的影响。塑料径迹探测器的蚀刻速率V与蚀刻温度T有如下关系: Plastic track detector charge resolution depends on the structure of the material itself is uniform, the stability of the etching temperature, etching solution concentration consistency. Especially in the cosmic ray experiments, the detector area is large, the number of large, requires large-volume etching groove, and sometimes need to be carried out in batches etching. Therefore, the control of the etching temperature and the distribution of the temperature in the bath have an important influence on the charge resolution capability of the detector. Plastic track detector etching rate V and etching temperature T has the following relationship:
