Methodological and Conceptual Progresses in Studies on the Latent Tracks in PADC

Modified structure along latent tracks and track formation process have been investigated in poly (allyl diglycol carbonate), PADC, which is well recognized as a sensitive etched detector. This knowledge essential to develop novel detectors with improved registration property. The structures of protons heavy ions (He, C, Ne, Ar, Fe, Kr Xe) examined by means FT-IR spectrometry, covering the stopping power region between 1.2 12,000 eV/nm. Through set experiments on low-LET radiations—such gamma ray-, multi-step damage electron hits was confirmed radiation-sensitive parts PADC repeat-unit. From this result, we unveiled for first-time layered tracks, relation number secondary electrons. We also proved that etch pit formed when at least two repeat-units were destroyed radial direction. To evaluate electrons around series numerical simulations performed Geant4-DNA. Therefore, are proposing new physical criterions describe detection thresholds. Furthermore, propose present issue definition threshold semi-relativistic C ions. Additionally, possible chemical criterion, density hydroxyl group suggested express response PADC.
