git clone https://github.com/jonlighthall/gfm7.git

Use Git to track changes in your local copy of the code and to receive updates.

Compiling the code

The executable is compiled using the commands in the makefile. Run these commands using the command make. The Fortran files used in compiling the executable are located in the src directory. A working example of the Windows executable gfm7.exe is included for reference.

Running the code

After the code has been compiled, run the program with the command ./gfm7. The program takes user input to provide the name of input file. The extension of the filename must be included.

Input

The following file is provided as an example input. 27Al.dat

Output

The following output files are generated

• 27Al.plt Not used.
• 27Al.grf Graphical output: prints the z-value of a 2D histogram of the focal plane.
• 27Al.mca Five rows are output for each event: the x- and y-position of the particle in the focal plane in cm; the final partical energy in MeV; the final charge state; and the time-of-flight in ns.
• 27Al.lis Not used.

The output files will have the same base filename as the input file.

Viewing the output

The macro mca2root.C has been included to convert a .mca file to a .root file populated with a TTree. The macro expects a file name output.mca. The file ren.bat has been included to rename the file. The To run the macro, use the following command.

root -l mca2root.C

This will creat a ROOT file named output.root with a TTree named t.
