On the use of Makrofol KG to study fission fragment angular distributions

Makrofol KG nuclear track detector processing and analysis is carefully regulated and assessed to reveal fission fragments’ tracks and their angular distributions. For this purpose, foils of this detector are irradiated by a thin 252Cf source and are subjected to chemical etching followed by a two-step sparking process. The detector efficiency as a function of fission fragment incidence angle and different etching parameters is carried out with a good reproducibility.
