مقارنة نظرية و عملية لمعلمات أثر نووي في كاشف الأثر CR-39 ناتج من جسيمة ألفا

Abstract EN

The aim of this work is to study some fundamental of tracks experimentally and theoretically in the detector CR-39 of thickness 250 μm, A computer program (TRACK-TEST) was used for calculating track parameters.

The results show that a maximum energy lost is occurred when the energy of alpha particles is about 5.1 MeV, The tracks tip for incident alpha energies 1 and 1.5 MeV appeared in a spherical phase which is called over etch step at etch time 2hr, while a sharp phase for energies 5.5,4.5,3.5,2.5 MeV was investigated, The maximum track depth was found experimentally is about )5.1( MeV, while the calculated value of this depth was found about )5.1( MeV.
