This file is the same as the one with the same on the web, at http://www.mc-set.com/readme.htm and applies to all versions of MC-SET.
These notes about the MC-SET Montecarlo Simulation of Electron Trajectories program, cover both the standard and the trial versions available for download from the internet.
Please read these notes carefully. If you are using a Trial version, read in particular the Administration Notes, and the separate Trial readme file.
The program will be installed in the following directories under the heading mc-set::
The total space required for the installation is about 10 megabytes.
During the install, the mc-set executable file will be checked using a cryptographic hash to make sure that it has not been changed. If there are problems, a suitable message will be displayed.
We recommend you check the downloaded file against the checksum hash file. For more details, see the notes in the download area of the web site.
Basic operation instructions are given in these notes. Additional information is available on the web site at www.mc-set.com. More information can be found in your local mc-set\Docs folder (under your My Documents folder).
The system does not have a manual at the moment, but it is hoped that you will be able to run it from an understanding of the physical problem that this program tries to simulate. The following notes try to explain some aspects of the program, and give some ideas about its workings.
If you have the full version of MC-SET you can receive the manual when it becomes available. This will be available both in electronic format, and as a cd with files in Acrobat format. Printed copies will be available at cost.
As an example of the program operation, the following is created after the installation and activation of the program on the hard disk:
(i) the program executables are in the \MC-SET subdirectory (under the Program Files directory, and is called mc-set.exe (this is the default installation path)
(ii) this readme.txt file is in the Docs directory, located in the mc-set\docs subdirectory under your own My Documents.
(iii) under the mc-set\ folder in My Documents two additional subdirectories exist: \DATA where the data used for the calculations is stored, and \RESULTS which stores them.
On first running the program sets the default locations for data, results and docs, in a special ini file. This is done using the Default Locations entry from the Options menu item. In this way, you will be able to access the sample data and result files that come with the program.
Have a look at the other options available, available under the various sub-menus in the Options main menu item.
The operation of the program uses the following elements:
a) material: contains constant physical data about a particular material, used in the definition of a specimen for the simulation
b) materials list: a file that contains various materials records
c) specimen file: contains layer(s) information, which have associated materials and also geometrical information
d) experiment file: contains a specimen name and the beam and instrument operating conditions. Contains also some selections with respect to the type of algorithms to use, and what kind of output is required. Various global settings that affect the experiment are setup globally, under the general Preferences menu.
The above are used to define a simulation run. The following files can be obtained from the simulation:
e) results file: contains a summary of the experiment, the material, along with some data that was calculated at the end of the simulation
f) energy file: contains a cube of energy data, which is the image of the beam energy dissipation volume. Size of this file is 4 MBytes , for a cube of sides 100 units. The extent of each unit cell is defined in the experiment file (plotting depth parameter).
g) excel files: when running dose calculations or ebic calculations (using the data saved in f) above) the output gets sent to the excel spreadsheet, and there it is displayed and stored. An excel macro manages all the plotting and various sheets related to each energy file. An example excel file is supplied that shows some stored data. Also, the pages that came with this diskette are actual excel printouts of the program output.
h) backscattered and transmitted electrons data file - text file with information about all backscattered and/or transmitted electrons
i) trajectories data file - text file with data about the electron trajectories and energies, used for the plotting of the simulation
h) trajectories graphics file - graphics image of the selected number of trajectories to be plotted, with parameters as setup in the Preferences menu option.
k) x-rays data files
The following gives an indication of possible steps to run the program:
You will find that the run command (the green triangle button in the toolbar) runs various functions: the same button runs the simulation, the ebic calculation, the electron dose calculation.
1) When saving data for a window make sure that the window is active, as indicated by the highlight of the title bar.
2) When creating new data files, you must enter the name of the file along with the extension for the type of file that is required.
3) When editing data for a specimen, you need to explicitly save the data after defining a materials file: this will update the values in the materials combo boxes, and allow you to select the layer material.
4) To change the position of the legend on the graphic display of trajectories click with the left mouse button at the desired location for the legend.
5) When using high values of zoom the shading of the layers does not display correctly, but this does not affect the trajectories display or the simulation results.
7) In order to obtain energy data the program needs to store the energy deposition cube in a drive that has enough free space: it needs 4 MBytes for each simulation.
8)The weighted average values of atomic number and weight need to be entered and checked for the compound materials. The density of these materials needs also to be entered in order to use them in the Monte Carlo simulations. After running simulations, please check (either in the simulation results window, or by exporting the results to a text file, or by running further calculations e.g dose or EBIC, that the material parameters used do make sense. The program includes some functions to calculate different atomic number averages; it is not clear as to which one is preferable.
1) The program will only run from the computer where it has been installed. It can not be copied to another computer or hard disk, or to another. If you want to install it on another machine, download a new setup file from the web site. From the original setup file file with the compressed files it is possible to install to any number of machines (but not possible to copy the installation from one machine to another)
2) As supplied the Trial program will have a limited life, and will expire after the evaluation period (usually 1 month). This condition can be remotely modified if you wish to do so. In this case, the normal demo cost will be applied (see the documentation supplied with the program for the various options available).
3) Telephone support is possible only to purchasers of the full version. For the trial (demo) versions, please use the Internet or e-mail support.
4) Price list: in GB pounds, not including VAT, where applicable, correct on November 2010:
(1) trial version: free (2) 3 months demo (long trial): 100.00 GBP (includes manual) (3) Standard version: 499.00 GBP
See the web site for further information about purchasing.
Options (3) includes support and updates for one year. For (1) and (2) the support is only via Internet e-mail, for (3) the support can be given by phone as well. After the first year, support and updates will be charged at 20% of the price of a new current copy of the software.
5) Please remember that the code for the program keeps changing, with different algorithms and more features continuously being added.
