First tries using McStas

[artus at obiwan.kri.physik.uni-muenchen.de]

Hello Kristian,

using xour component Guide2 for different coatings for left/right and
top/bottom faces of a guide I have now a first set up which could be
compared to a calculation with the program Beamline written by Jeremy Cook.
Beamline is able to compute absolute fluxes. Is there any possibility
to calculate absolute fluxes with McStas?
Another possible comparison is the transmission. Within Beamline, 
the transmission is the number of neutrons detected divided by the
number of neutrons entering the first guide section. To calculate an
"equivalent" transmission with the output of McStas I divided the
value mon_I by the solid angle at the source and divided the resulting 
value by the number of started neutrons. Is that correct?

At the moment I'm trying to compare the profiles. Unfortunately we
don't have MATLAB so I need a workaround. The spatial distribution of
neutrons at the detector is no problem. How can I get the angular
distribution with McStas?

Best regards,

Georg
