The bismuth layer O234200100013 was deposited by vacuum evaporation on one of the O234200100014 Makrofol foils, then it was covered by an other O234200100015 Makrofol layer. Finally, the targets were packed O234200100016 in vacuum-sealed plastic bags. O234200100017 DETECTOR (TRD) Makrofol track detectors of size 40x30x0.2 mm3 O234200100018 METHOD (INTB,SITA) The sandwiched targets were irradiated by O234200100019 alpha beams with normal incidence. After the O234200100020 irradiation, the targets were dissolved by nitrate O234200100021 acid, and the Makrofol detectors were etched in two O234200100022 steps in a 20% NaOH solution at 60 degrees of O234200100023 Celsius. The etching steps were 25 and 75 mins long, O234200100024 respectively. After each etching step, the detectors O234200100025 were rinsed with water and alcohol, then evaluated. O234200100026 The evaluation was done by analyzing the tracks under O234200100027 optical microscope, and by scanning the targets.
