The USRYIELD card gives exactly an histogram of LET. The same card can
be used to produce histograms of many other quantities , like energy,
charge and so on, at the boundary from one region to another.
In the case of LET, the "bins" will be in keV/(micron g/cm^3 )
and the "contents" will be NORMALIZED to unit interval of your second
variable : be careful.
To partially answer to the old posting (sorry..): the 6th what of the
USRBIN card must contain the code of the material in which the LET has
to be calculated: it is NOT taken to be equal to the one of the ingoing
region, and if absent will be put equal to Hydrogen (material number 3,
the first non-vacuum in fluka)
If you have doubt on how to set the USRYIELD card, please send the input
file so that we can check. Try also to have a look at the manual, and at
the Scoring lectrure of the fluka course.
..I do not know whether our definition of LET spectra is different from
yours..simply because I do not know what is your definition..
