“…Superheated drop detector (SDD) is known to detect neutrons, gamma-rays and other charged particles under different operating conditions [1][2][3][4][5]. It is also one of the promising detectors in search for WIMPs (Weakly Interacting Massive Particles), one of the favored candidates for cold dark matter [6][7].…”

“…The details of evaluating neutronnucleus elastic scattering cross-section, nucleation efficiency and count rate in the present case, have already been described elsewhere [16,[18][19][20]. The experimentally observed variation of integral (accumulated) count as a function of exposure time for both R134a and R12, irradiated with Am-Be neutrons at an average room temperature of 32.5 • C is shown in figure 1.…”

Superheated emulsion detector is known to detect neutrons, γ-rays and other charged particles. The present work includes the study of nucleation efficiency of superheated drops of one of the CFC-free liquids, R134a (C2H2F4), to fast neutrons, its response to γ-rays from 241 Am and 137 Cs and compare its nucleation efficiency with that of R12. The observation indicates that because of the presence of hydrogen, the nucleation efficiency is less in R134a than in R12 in the present neutron energy range of consideration. R134a is one of the most environment-friendly, commercially available liquid that is suitable for superheated drop detector, specially in neutron dosimetry and one needs to investigate it in detail.

The nucleation parameter for heavy-ion induced bubble nucleation in superheated emulsion detector

et al. 2013

View full text Add to dashboard Cite

The values of the nucleation parameter, k, for bubble nucleation induced by high energy heavy ions 12 C (180 MeV/u), 20 Ne (400 MeV/u) and 28 Si (350 MeV/u) in superheated emulsion detector are determined by comparing the experimentally obtained normalized count rates with those obtained from simulations done using the GEANT3.21 simulation code. The results show that the nucleation parameter depends on the mass number of the incident heavy ions, and decreases with increasing mass number.
