Abstract
Samples of barium phosphate (BP-1) glass detector were irradiated by 238U (11.4 MeV/u) ions from the UNILAC accelerator, at GSI, Darmstadt, Germany. Etching characteristics were studied using HF (48 vol%), NaOH (6.25N) and KOH (6.5N) at different temperatures. The sensitivity, (=tb) of BP-1 glass is found to vary between 63 and 33 between temperature range 40–70°C. The experimental range of 238U (11.4 MeV/u) ion in BP-1 has been determined and compared with the theoretical range values from different formulations. For study of annealing characteristics, both isothermal and isochronal experiments were performed on BP-1 glass irradiated with 238U (11.4 MeV/u) and fission fragments from 252Cf source. The annealing kinetics of heavy ion damaged BP-1 glass is explained by using different empirical formulations. The activation energy of annealing for heavy ion damaged BP-1 glass is found to be 0.405 ± 0.005 eV.
