Extension of alpha particles in CR-39-etched track depth model to heavier ions

Abstract

In this paper, the previous modeling of protons and alpha particles tracks depth in CR-39 nuclear track detectors was extensively extended to describe tracks of heavier ions. These ions include deuteron, lithium, boron, carbon, nitrogen and oxygen. Based on a compilation of published experimental results related to these ions, a set of empirical fitted model parameters is obtained for each type of ion. The A dependence of these model parameters is obtained.

Alpha particles energy estimation from track diameter development in a CR-39 detector

“…However, the saturation length itself is also energy dependent. Even in the absence of complete analytical detector theory, suitable empirical modeling of these two quantities can be employed to generate energy metrics (Nikezic and Yu, 2006;El Ghazaly, 2012, Azooz et al, 2012aAl-Jubbori, 2013). However, such longitudinal tracks profile measurements usually involves more effort and instrumentation compared to simple tracks diameter measurements (Dörschel et al, 2002;Yu et al, 2004;Borghesi et al, 2007;Johnson et al, 2009) …”
