Hello Kristian,
now that I'm using the E_monitor I'm a little bit confused about the
output. The E_monitor's output consist of 4 numbers in the file. They
should be Energy, number of neutrons, sum of the weights and sum of
the squared weights (E, N, I, M2). I'm not sure how to read these
values when I use Source_flux. Then M2 is much higher than I.
E.g. source_flat:
80.992 425 0.00177358 2.13035e-08
same file, but source_flux (flux=3.63E+12):
80.992 384 127625 1.14823e+08
The values for I can be transformed using flux and solid
angle (2.387E-4). How about M2?
What are the units of I and M2 for any monitor when I use source_flux?
I assume it is n/cm**2/s/AA?
According to the manual all monitors should give N, I and M2 in the
output. But using PSD_monitor or Divergence_monitor I have only one
number in the file? The E_monitor is the only one which produces all 3
numbers?
Here two smaller remarks for any future revision of the manual:
4.5.6. not dE but nchan hast to be given
4.1.2 wrong formula for I in last sentence
Best wishes,
Georg
