| Description | Journal: Iop Conference Series: Materials Science and Engineering A lot of research was focused on studying the engineering shape of the impact and its development and finding its parameters. It was based on pictures of the side effects of the effects formed in the detector as a result of the detector’s etching. Obtaining pictures of the side effects of the effects to measure their lengths is a difficult process compared to its diameters. There are many methods used to find Bulk etch rate VB including gravimetric method or thickness difference; but we will use in this research an alternative method to find VB which is the maximum value method for saturation of the effect length “Lmax-method”. Using the source Am241 (1μCi) emitting alpha particles in irradiation of the PDAC CR-39 irradiation With MeV energies (2.3,3.3,4.3), the detectors etching by NaOH aqueous solution at different concentrations (N: 6,7,8) at a temperature of 70±1 °C, we suggested in our research a D-Le calibration method that is based on direct experimental measurement of the diameters of the projected effects in Detector instead of lengths. An empirical relationship was used to find VB, which depends on the maximum values of saturation of effects lengths and their saturation times. The results we obtained for VB values at the concentrations used were (1.199,1.490,2.184) μm $h^{−1}$ in order and they correspond well to the values resulting from different methods, it is observed The Bulk etch rate increases with the concentration of the abrasive solution, and the maximum values of saturation of the effect length are directly proportional to the energy of the bombing particles and the time of saturation of the impact lengths. |
