I couldn't find anything about this card, unfortunately, which guide do you use in the guide?Aaron Barnard said:The card you need to add to the input file is 'STOPHZ'. This card is used to specify the stopping power for a single energy value. You can find more information about this card in the FLUKA manual.
In FLUKA, stopping power for a single energy value can be found by using the USRYIELD card. You need to set up a simulation where you specify the energy of the particle and the material through which it is passing. The output will provide you with the stopping power at that specific energy.
To calculate stopping power in FLUKA, you need to use the MATERIAL card to define the material, the BEAM card to specify the particle type and energy, and the USRYIELD card to request the stopping power calculation. Additionally, proper geometry setup using GEOBEGIN and GEOEND cards is required.
Yes, you can calculate stopping power for multiple energies in a single FLUKA run by setting up different BEAM cards for each energy value and corresponding USRYIELD cards to record the stopping power for each energy. Alternatively, you can use a single BEAM card and a USRYIELD card with energy bins covering the range of interest.
The output of the USRYIELD card will typically be in the form of a text file that contains columns of data. These columns will include the energy values and the corresponding stopping power values. You will need to refer to the FLUKA manual to understand the exact format and units used in the output file.
Yes, FLUKA can be used to compare stopping power in different materials by setting up separate simulations for each material. You will need to define each material using the MATERIAL card and run the simulations with the same particle type and energy. The stopping power for each material can then be extracted from the USRYIELD output and compared.
