Dear Ross,
How about the LP factor/monochromator angle if using Gobel mirror in
my D8 system?
Thanks!

Dear all,
Just to be complete, the Topas technical reference manual also gives the
LP values for a few other common monchromators:
Pg109
"Values for most common monochromators (Cu radiation) are:
Ge : 27.3
Graphite : 26.4
Quartz : 26.6"

Hi Xiujun,
Jon is correct, but
factor in the Rietveld refinement
Sounds like the parameter is the monochromator angle you would need to
use to convert an unpolarised beam into a beam with the polarisation
state you have (eg, 90 degrees gives 100% polarised). Don't confuse this
with the actual monochromator angle at the synchr
