Re: Scoring Low-Energy Electrons

Dear Johannes,

first of all, FLUKA cannot transport electrons at energies below 1 keV:
1 keV is the lowest limit.

Concerning MULSOPT, to activate single scattering you must set SDUM=GLOBAL and
WHAT(6) > 1000.
I don't know what FLAIR does (it should work, but if it doesn't, you can
always override FLAIR writing the correct card by hand...)
