    This has nothing to do with your problem (probably), but I am wondering 
why you (as well as a number of others) insist on doing 
d5->SetCurrent(run->GetD5Set(), run->GetD5Pol()); in your code.  Those 
exact statements are done in BrMagnetVolume and doing them in your code 
adds extra room for bugs and confusion.  The only requirement is that 
the proper run has been selected.  If you do not do your above run and 
things don't work, then something else is wrong anyway.
