V-function to investigate tracks of the alpha particle irradiated CR-39 detector

Updates to TRACK_TEST and TRACK_VISION Computer Programs

“…The computer program TRACK_VISION was developed in 2008 [10] to model the optical appearances of such tracks. In the revised version of TRACK_VISION, the two V functions for the CR-39 detector established by Al-Jubbori [19] and Hermsdorf [20] were also added, and the Makrofol option was also enabled. To differentiate between the original and revised versions of TRACK_VISION, the current revised version is entitled TRACK_VISION 2.0, and both the original version TRACK_VISION and the revised version TRACK_VISION 2.0 are available on the website http://www.cityu.edu.hk/nru/Track_Vision.htm (accessed on 13 Feb 2021).…”

“…The computer program TRACK_TEST was first developed in 2006 [ 9 ] to model alpha-particle track profiles that enable the determination of parameters including the lengths of major and minor axes, as well as the depths of the tracks. In the revised version of TRACK_TEST, two V functions were added, which were taken from the research works of Al-Jubbori [ 19 ] and Hermsdorf [ 20 ]. Moreover, the Makrofol option was added by adopting the V function from Stajic et al [ 21 ], with some modifications.…”

“…In this revised version of TRACK_TEST, two new V functions (expressed through the residual range R′, which is defined as the distance from a specific point on the particle track to its end point) were added and enabled. The first added V function was adopted from the work of Al-Jubbori [19] in the form…”

“…In this revised version of TRACK_TEST, two new V functions (expressed through the residual range R ′, which is defined as the distance from a specific point on the particle track to its end point) were added and enabled. The first added V function was adopted from the work of Al-Jubbori [ 19 ] in the form V ( R ′) = 1 + exp [– a 1 R ′ + a 2 − a 3 / R ′ + a 4 / R ′ a5 ], with the constants a 1 = 0.098, a 2 = 1.86, a 3 = 37.78, a 4 = 36.98 and a 5 = 0.98 obtained by fitting the data provided by measuring the average lengths of the tracks (observed using an Optika B-193 microscope, Optika, Ponteranica, Italy) for different alpha-particle energies and etching times. In the revised TRACK_TEST, this function can be invoked by typing No.…”

Strong etching formulation (time and rate) for PADC with deep depth bulk etch rate study

“…The standard procedure when using solid-state nuclear track detectors (SSNTD) is to reveal latent ion tracks by operating a chemical etching which makes them visible under the optical or atomic force microscope. Commonly used etching solutions in the literature are alkaline etchant such as NaOH or KOH with concentration range of 6-7 N at temperatures of 60-70 °C [1][2][3][4][5][6][7][8][9][10]. However, a new etchant solution composed of NaOH with different amounts of alcohols (ethanol and/or methanol) has been used as a strong and active etchant [11][12][13].…”
