Abstract
The depth dependent track etch rates of two types of CR-39, TASTRAK and BAR YOTRAK, for Li-7 ions with incident energies of 4.82, 6.75 and 10.77 MeV ha ve been evaluated from track length measurements. The pit lengths versus th e etching time obtained by three different laboratories have the same trend , but did not agree completely. The differences can be attributed to an err or margin of less than one decimal point in the etching temperature. Signif icant deviations were also present for the assessed track etch rates. Most of the deviation was attributed to the derivation step of the growth curves . A sufficient amount of data and reasonably smooth growth curves were requ ired near the Bragg peak in order to make a precise estimation. (C) 2001 El sevier Science Ltd. All rights reserved.
