Hi Andrey,
I think that you forgot to attach the input file.
Anyway, one of the reasons why you don't see a signal may well be the
energy of your protons (~10 eV?), which is below the transport threshold
for charged hadrons (1000 eV, please see
http://www.fluka.org/fluka.php?id=3Dman_onl&sub=3D3), which means that
your protons are killed as soon as they are shot and they don't reach
your detector.

Subject: TCQUENCH parameters
=20
Hello,
I'm somehow stuck with the TCQUENCH option in Fluka...
Could you please explain what is exactly the reference time from which
the WHAT(1) seconds are counted. Is it a time when primary particle
originated, or a time when the binning in question scored it's first
event? Or what?
I need to simulate a TOF detector and I started with a simple model
(attached is my input file), where non-relativistic proton beam (~10 eV)
originates in vacuum and travels towards the area (100 cm away) where I=20
score protons' track-lenght density with the USRBIN option. Since this
is a non-relativistic case I use classical formulas to estimate time for
my primary beam to reach the detector, but I can see nothing in the
detector with these times. Increasing scoring time 3 orders of magnitude
does help to score something, but still I'm not clear what is wrong.
Well, it may be that I miss out something very simple but in any case I
would really appreciate your help as I'm stuck with it %)
Thanks in advance,
Andrey.
