Abstract:
The effect of the host medium viscosity of the superheated drop detector on formation and stability of Freon-12 bubbles produced by neutron irradiation has been investigated. By variation of the acrylamide and methylenbisacrylamide concentrations on monomer solution, different polyacrylamide gels with various viscosities of 1 up to 13 Pa-s were prepared. The gels were utilized to prepare the superheated droplet detector. The irradiation results of the prepared superheated droplet detector using an 241Am-Be neutron source and the 2.89 MeV neutrons obtained from the d-d neutron generator showed that the formed bubbles in the fabricated detector, based on non-crosslinked polyacrylamide gel, with the viscosity of 5-6 Pa-s were stable and could be counted after irradiation with the naked eye. The number of bubbles were found to be proportional to the neutron fluence.
