Contribution
It introduces a pulse height analysis technique at specific temperatures to effectively discriminate between neutron and gamma-ray events in SDDs.
Findings
Pulse height varies significantly between neutron and gamma-ray events.
Temperature-dependent pulse analysis improves discrimination accuracy.
Method enhances detection specificity for mixed radiation fields.
Abstract
Superheated drop detector (SDD) consisting of drops of superheated liquid of halocarbon is irradiated to neutrons and gamma-rays from 252Cf fission neutron source and 137Cs gamma source separately. The analysis of pulse height of the signals in the neutron and gamma-ray sensitive temperature provides strong information on the identification of neutron and gamma-ray induced events.
