Abstract
In this work chemical etching characteristic of Makrofol-E SSNTDs has
been studied, in details. A new suggested etching condition has been introduced
and found to work successfully in background- track reduction and in registered
energy- window improvement. An etchant concentration of 1.8 N (KOH
+C2H5OH+ H2O) at 70 ˚C was used and alpha tracks of energies range from 1 to 5
MeV were recorded and surrounded with a noticeable (or, at least, distinguishable)
low background level. Makrofol-E detectors were exposed to 22Ne, 40Ar, 65Zn and
129Xe ions with different energies and track parameters were then been measured.
Diameters, densities and lengths of tracks were determined and various
relationships were then extracted along with the evaluation of different detectors
efficiencies. The dependence of the response function, V on the dose imparted to
the detector was found and took the form
V = 0.21 D (μGy) + 1.894
All results are discussed within the frame work of the theory of track formation in
solid.
