I'm using the USRBDX card to score the neutron fluence resulting from a
2.8MeV proton pencil beam hitting a Lithium-7 target. The resulting
data is compiled using the usxsuw command and the *_sum.lis and
*_tab.lis files produced.
The problem is that the double-differential fluence is reported (as
non-zero) in the *_sum.lis file, but all entries are then printed as
zero in the *_tab.lis file. The differential fluence is reported fine
in both files.
Has anyone any ideas what I may be doing wrong?
So far I have tried increasing the WHAT(3) and WHAT(6) value from their
defaults of 80.0/100.0 seconds in the START card, but this then results
in the whole run terminating before the requested 1,000,000 histories
have been transported.
Any pointers would be greatly appreciated!
