I am coming back from few weeks ago when I asked a question regarding the scoring of LET and Fluence.
I managed to perfom the simulations but after analyzing the results it seems to me that the LET values are much smaller than expected - few orders of magnitude. Did I oversee a normalization or did I get the units wrong?

I am attaching the input and flair project alongside with the plots that I have.

Regarding your approach, you’re attempting to observe the LET deposited energy by performing a transversal integration of the USRBIN result. There are two key elements missing in your normalization:

The surface area of the USRBIN slice (since you’re doing a projection, you should multiply the results by the transversal dimensions of your USRBIN, i.e., 4*4 = 16).

I also noticed that you organized your run using several if/elif conditions. While this works, it’s not the most efficient approach. I’ve reorganized the different energy cases using Flair’s function evaluation capability (F3.6} Function evaluation). You can find an updated flair file here:

The conversion from GeV/cm to kev/um I just figured it out but it’s so good to have a confirmation on that.
For the surface area I thought that in this case it is done automatically but thank you so much for the clarification.

I will check the input that you sent when I get into the office. The if/elseif trick was the only idea that I had so that I don’t have 9 almost identical simulations
