Determination of the detection threshold for Polyethylene Terephthalate (PET) Nuclear Track Detector (NTD)

Distinct step-like changes in G values for the losses of typical functional groups in poly(ethylene terephthalate) along boron ion tracks around the detection threshold

“…Poly(ethylene terephthalate), PET, has been recognized as an etched track detector with relatively high detection thresholds depending on the industrial products (Bhattacharyya et al, 2016;Drach et al, 1987;Somogyi et al, 1976). Stacked PET detectors with different kinds of detectors of poly(allyl diglycol carbonate), PADC, and polyimide (Kapton) have made it possible to identify the nuclear charge of heavy ions from the intense laser plasma in complex radiation fields (Nishiuchi et al, 2015).…”

“…Detection threshold of PET is very high; it detected fission fragments but did not detect alpha particles when exposed to Cf 252 source [1]. We have optimised the etching conditions and characterization and calibration have been done for this detector using several different ions from accelerators in India and abroad [2][3][4][5]. Now PET is a well established passive detector.…”
