Abstract
Abstract A knowledge of the charge resolution power of polycarbonate detectors for ultra-heavy ions (Z ≥ 30) is essential to establish the cosmic ray spectrum in the UH region and to obtain useful information on nucleosynthesis and propagation mechanisms. In this paper, a systematic study of LEXAN polycarbonate response to relativistic (⋍ 1 GeV/N) gold ions (Z = 79) is presented. The influence on the detector sensitivity of etching conditions, such as NaOH concentration and bath temperature, is explored and the conclusion is reached that detector response is rather independent of them all, in agreement with the well known results at lower ionizations.
