Dear Yann
am I wrong or your input has a 800 um thick window rather than a 80 um
one?
The window thickness is defined by
XYP 4 +0.080
and 0.08 cm corresponds to 0.8 mm -> 800 um if I am not wrong (check
please!)
If so, your 10 MeV beam is probably ranging out in the window (it would be
better anyway to lower the proton transport threshold to 100 keV
using PART-THRES, since the default CALORIMETRY is setting it at 1 MeV)
I lowered the thickness to 0.008 cm and now roughly 660 keV are in the
window and rest goes thru (reasonable according to my dE/dx tables).
Ciao
Alfredo
