“…A number of these difficulties can be resolved via using Superheated Drop Detectors (SDDs) which are frequently utilized for neutron spectrometry and dosimetry. These detectors that are developed based on a principle that was recognized in the 1950s [5], comprises tiny superheated drops distributed uniformly in a host gel medium [6][7][8][9]. If the charged particles generated due to neutron interactions with superheated liquid nuclei have sufficient stopping power and consequently sufficient energy (greater than a threshold value), cause the drop to evaporate and a visible bubble will be formed in the detector [6][7][8][9].…”

In this paper, the response matrix of Superheated Drop Detector was analyzed and investigated using Evaluated Nuclear Data. Elastic, nonelastic and total neutron cross sections were extracted and used for calculating the probability of the production of charged particles as a result of neutron interaction with superheated liquid nuclei. The values of the response functions in each energy are proportional to the probability of the production of charged particles. It was proposed that the response function can be represented as the multiplication of the total neutron cross sections by a monotonic probability function. The parameters associated with this function change with changing the physical properties of the detector such as temperature or external pressure. The growth rate of this function decreases when the temperature decreases or the external pressure on detectors increases due to increase in threshold energy for the generated charged particles. So the growth rate and shape of this function are set by parameters which are dependent on the physical properties of Superheated Drop Detectors.
