Evaluation of the sensitivity function V for registration of α-particles in PADC CR-39 solid state nuclear track detector material

Comparative analysis of CR-39 sensitivity for different sets of measurable track parameters

“…All obtained V Ddl values were attributed to the a-particle's calculated residual ranges R in CR-39 in order to compare the V(R) function with analogous data reported earlier in Hermsdorf, (2009a). It was assumed in calculation that measured V Ddl value corresponds in the best way to the half visible track length AB (point C in Fig.…”

Digital holographic microscopy for recording and analysis of 3D images of etched tracks in LR-115 SSNTD

“…The bulk etch rate (V B ) is relatively easy to measure by direct and indirect methods, but information on the track etch rate (V T ) is relatively scarce and very scattered. Since DHM allows the 3D visualizing of etched tracks with good accuracy, track etch rates can be determined by the time dependent track length method [33,34] or by the 3D-track wall method [35]. For the last case, track wall coordinates should be extracted from reproduced 3D track images by means of image analysis and computer calculations.…”

Computer program for the sensitivity calculation of a CR-39 detector in a diffusion chamber for radon measurements

“…The discrepancy between reported results is probably caused by different types of CR-39 used in examinations (prepared from various raw materials or with a somewhat different procedure), as well as by methods applied in measurements. Recently, an excellent critical review of a published V function was given by Hermsdorf, 21 Hermsdorf and Hunger, 22 and Hermsdorf and Reichelt. 23 In this work, the following V functions are built in the software: N 0 1 function was published in Durrani and Bull 24 and Green et al 25…”

“…with constants A 1 = 0.069 μm −1 , A 2 = 1.1784, and A 3 = 0.6513 μm −1 and N 0 4 has the same form as function N 0 3 but with slightly different coefficients 28 A 1 = 0.06082 μm −1 , A 2 = 1.119, and A 3 = 0.8055 μm −1 . And finally function N 0 5 is taken from Hermsdorf 21 and has the form The user can choose any of these functions by simply changing the last number from 1 to 5 in the file INPUTCR.DAT. Application of another function number will probably generate an error.…”
