Abstract
Fast detection of alpha particles in DAM-ADC nuclear track detectors using a new chemical etchant was investigated. Cf and Am sources were used for irradiating samples of DAM-ADC SSNTDs with fission fragments and alpha particles in air at normal temperature and pressure. A series of experimental chemical etching are carried out using new etching solution (8ml of 10N NaOH+ 1ml CH OH) at 60°C to detect alpha particle in short time in DAM-ADC detectors. Suitable analyzing software has been used to analyze experimental data. From fission and alpha track diameters, the value of bulk etching rate is equal to 8.52μm/h. Both of the sensitivity and etching efficiency were found to vary with the amount of methanol in the etching solution and etching time. The DAM-ADC detectors represent the best efficiency applicable in detectors in the entire range of alpha energies (from 1 to 5MeV). The activation energies of this etchant have been calculated; track activation energy, E , has been found to be lower than the bulk activation energy, E , for the DAM-ADC nuclear track detectors. These results are in more agreement with the previous work. 252 241 3 T B
