| Summary: | age of the detectors is also a parameter to be considered. also demonstrated a dramatic effect of the age of the etching appeared that, from 0 to 1.31 mg.cm-2, the thickness has an association with an established etching process: 145 minutes at 60'C in a 10% NAOH solution. This study also presented an attenuation effect of the oxide layer was performed. It comparisons could be performed. constants This proved that the oxide layer thickness of the experiments showed that the relative position (horizontal or important effect on the exposure rate. However, for Mg.CM-2. Therefore, the comparison initially planned could now be continued. However, this study strongly suggests that of the etching solution to the detector area to be etched. Once the etching process was improved and set, a study of the opportunity to obtain more knowledge of the etching process, particle detectors. The SSNTD to be compared were different Path6 LRI 15 films (cellulose nitrate) were used, in polycarbonates and a cellulose nitrate detector. For this purpose, an uranium foil was used as the alpha particle resulting in the improvement of the etching efficiency. The several Solid State Nuclear Track Detectors (SSNTD) as alpha should be studied for the LR I 15 films before additional solution on the etching efficiency and also showed that the source. The foil created new problems which needed to be studied in detail. Among these problems, the effect of the surface was the most important. To study this effect, Kodak- the effect of the age of the detector and the ratio of the The original goal of the present thesis was to compare thickness of the oxide layer on the uranium metal foil thicknesses above this value, the exposure rate remains uranium foil should not be of concern once it reaches 1.31 vertical) of the film in the etching bath was important. It volume of the etching solution to the area to be etched which required greater study, such as the ratio of the volume With these experiments, other parameters were identified |
