The Superheated Liquid & Radiation Detection

Mala Das

The liquid, maintaining its liquid state above its boiling point is said to be superheated. Superheated drop (bubble) detector consists of drops of such superheated liquid suspended in another liquid holding medium. These are threshold detectors and the threshold energy depends on operating temperature and pressure. It serves as a useful detector in different fields of radiation detection, such as for neutrons and cold dark matter search. The intrinsic insensitivity to most undesirable backgrounds opens the advantage of using it as neutron dosimeter especially for accelerator site where there is a strong background of gamma rays. The estimation of energy of the incoming radiation, the nucleation parameter and the practical application of the detector will be discussed in this talk.
