Dear FLUKA experts,

     I wonder whether u can have a look at the attached picture.
I have a thin window 100cm x 100cm x 1.5cm of gas volume Argon at 1 atm.
I hit with an electron source of 500 MeV from distance of 50 cm vertical
in the centre that gas window.
The energy deposition is given in the attached plot.
the maximum is around 2.8 keV probably the mip energy BUT there is
a shoulder around 8 keV (??)
I shitch off some fluka procedures BUT in vein...
I search at experimental data too but nothing comes out...

Is it any physics for that?

thank you very much in advance

Best regards

Georgios
