Track-registration-and-development characteristics of CR-39 plastic track detector

The response of CR-39 nuclear track detector to 1–9 MeV protons

“…18 Studies of the CR-39 efficiency for detecting protons as a function of incident angle in the energy range of 1-10 MeV have also been undertaken, as well as preliminary studies which characterized the track diameter as a function of incident mean proton energy. 17 In this work, we present the TasTrak CR-39 track diameter response curves to protons as a function of energy, including a study of piece-to-piece variability in addition to the effects of etch time and etchant temperature. We also present the results of a 5-year study of the effects of aging of CR-39 using 5.5 MeV alpha particles.…”

“…Previous work, utilizing various types of CR-39, have studied the effectiveness of various track etchants, 11 and have looked at the CR-39 response to alpha particles, [12][13][14] electrons, 15 gammas, 16 fission fragments, 17 and neutrons. 18 Studies of the CR-39 efficiency for detecting protons as a function of incident angle in the energy range of 1-10 MeV have also been undertaken, as well as preliminary studies which characterized the track diameter as a function of incident mean proton energy.…”

Impact of x-ray dose on the response of CR-39 to 1–5.5 MeV alphas

“…CR-39, a transparent SSNTD with chemical composition C 12 H 18 O 7 , is particularly well suited for detecting nuclear particles because its induced tracks are revealed optically by etching with sodium hydroxide. These tracks can then be identified with an optical microscope with 100% efficiency for many charged particles that are normally incident to its surface (such as protons in the energy range 0.5 to 8 MeV 4,6 ). The uniquely high sensitivity of CR-39 has made it the detector of choice for light ion studies because the ionization levels of protons and deuterons are typically below the response thresholds of other detectors 9 .…”

“…In many scientific disciplines, including Inertial Confinement Fusion (ICF) research, charged particles and neutrons are often studied with solid-state nuclear track detectors (SSNTD) [1][2][3][4][5][6][7][8][9][10][11][12] .
