(1) Program download

Download the program only if you agree to the above conditions of use: Download

The program is distributed as a zipped file called vision1.zip. Unzip all files in a single directory.
You should have the following three files:

Track_vision_1.exe (this is the main program)
Rang_cr_srim.dat (this is a data file, which you should NOT modify)
Input.dat (this is the input file, which you can change according to your needs)

(2) Input file

The first 4 lines in the Input.dat file will be used:

line 1: energy of alpha particle (in MeV);
line 2: time of etching (in hours);
line 3: the bulk etch rate V_b (in mm/h)
line 4: incident angle (in degrees) (normal incidence = 90^o)

For example, the supplied input file is for calculations for normally incident 3-MeV alpha particles in a CR-39 detector which has been etched for 12 h at a rate of 1.1 mm/h

3.
12.
1.1
60.

When you run "Track_vision_1.exe", the following screen will appear: 

Type "F" and hit return to use the "Input.dat" file.

(3) V functions

The following screen will then appear: 

Four forms of the V function for the CR-39 detector are provided and the user can choose one. The first provided function was published by Durrani and Bull (1987) and the second by Brun et al. (1999). The functions are characterized by the fitting coefficients. The user can adopt the default coefficients, i.e., those published in the original references, or input some values chosen by the user. In this way, different functions can be tested by the user. Whenever a user chooses some other coefficients, the program will calculate the new V function with these coefficients and plot it on the screen. If the function is smaller than 1 at some points or if it has no maximum, the program will stop and respond ?i style="mso-bidi-font-style: normal">this function cannot work? Some other possible problematic functions are also disabled. The third V function (Yu et al. 2005a) and the fourth V function (Yu et al. 2005b) were determined by our group and only the default constants can be used for these functions. 

As an example, choose the second function by pressing "2", and then "D" for default constants.

(4) Fineness of graphs

In the following screen, the program prompted: 鐈ow many horizontal planes intersecting with the track do you wish??Try "100".

[This question is related to the 3-D calculations. The user will define the number of equally spaced horizontal planes that intersect with the track body, including the last one which intersects the deepest point of the track.]

The next question from the program is 鐈ow many points per one intersection?? Also try "100".

[The number input here will define the angular increment in the rotation of the track profile points around the particle trajectory. If the track dimensions are expected to be larger (say 15 to 20 mm in depth and the opening), the user should choose a larger number of planes and points, e.g., both between 50 and 200. On the contrary, for smaller tracks (say smaller less than a few mm in depth and the opening), a lower number of planes and points will be a better choice (in some cases 10 points will be sufficient to generate realistic images).]

The following screen will then appear: 

Choose (2) for a medium fine graph. 

[The fineness of the graphs is related to the number of points that represent the track profile and contour. A larger number of points will result in a longer calculation time.]

(5) Final outputs

The program outputs the track depth. The program also plots on the computer screen the following: the initial detector surface, the detector surface after etching, the profile of the track, the contour of the track opening, the trajectory of the particle as well as the scale (the vertical bar):

Press ENTER to get the track appearance: 

The major and minor axes are also given. After 10 s, there is an option to close the screen.

(5) Output files

After running the program, four output files will also be written to the same directory where the program has been installed. The first file (TRACK_COORDINATES.dat) gives the coordinates for the profile of the track. The second one (Contour.dat) gives the coordinates for the track-opening contour. The third one (3_D.dat) gives the track coordinates in three dimensions. The fourth file (BE.dat) gives the brightness of the elements.
