each instrument should have his own optmized file
Dear John
I agree with Francesco. In particular the values of the parameters alp, bet_0
and bet_1 are related to the material and dimensions of the cryogenic
moderators for the neutron source and should not be refined, while the sig_j and
gam_j
Rietveld List,
I have asked this before, but I'm asking again just by the off chance that I
could find a solution. Can anyone help me with respect to an instrument
parameter file that I can use with some neutron scattering data from a pulsed
neutron source?
Then problem is that I am unable to
Dear John,
I think that each instrument should have his own optmized file, due to its
profile function, but if you want to see some parameter files for neutron
powder diffraction from a pulsed source you can find them at

John,
As was said by Francesco, you really must go back to the instrument
responsible for the diffractometer you used to collect the data for that
instrument parameter file. An old example of such a file is
\gsas\example\inst_tof.prm (the instrument doesn't exist any longer),
however iparm files
