Dear Steffen,

If you are interested in folding ion fluence spectra with stopping powers you might want to consider to score directly LET (at surfaces) via the USRYIELD card. This is certainly the preferred way to go, as the same stopping powers are used as for transport and hence your results are fully consistent.

Apart from this, scaling from the stopping powers for HEAVYION in the output file (which are for the beam particle) to other ion species shouldn't be done by simply applying a scaling factor since different higher-order terms enter with different factors (powers of Z). One (tedious) way to get stopping powers for different species could be to run simulations for different ion beams and print the stopping power for each case.

Cheers, Anton

Subject: [fluka-discuss]: How to scale energy loss table for HEAVYION?

When requested (SDUM = PRINT for DELTARAY), FLUKA prints the dE/dx tabulations for the corresponding materials. I am interested in using those values for postprocessing scoring results (energy distributions) with consistent stopping powers in the case of HEAVYION. Does anyone if there is any documentation on how those values have to be scaled (by mass/charge) to cover different ions (charge >= 3)? I tried several (common) approaches but without any reasonable results.

Best regards,

Steffen
