The response of superheated droplet detectors (SDD) loaded with four different active liquids, R-12 (CClF), R-114 (CClF), R-134a (CHF) and R-610 (CF) have been studied to obtain the gamma ray detection threshold temperature (T) of the respective detectors. A Cs gamma ray source is used for this study. To obtain T from the experimental data a phenomenological model has been used. Result indicates that T maintains a linear relationship with the limit of superheat (T) of different active liquids used in SDD. It indicates that the limit of superheat of a liquid can be used for the prediction of its gamma ray detection threshold temperature.
已对装有四种不同活性液体（R - 12（CClF）、R - 114（CClF）、R - 134a（CHF）和R - 610（CF））的过热液滴探测器（SDD）的响应进行了研究，以获得各探测器的伽马射线探测阈值温度（T）。本研究使用了一个铯伽马射线源。为了从实验数据中获得T，采用了一个唯象模型。结果表明，T与SDD中使用的不同活性液体的过热度极限（T）保持线性关系。这表明液体的过热度极限可用于预测其伽马射线探测阈值温度。
