<p>Thank You Brian,</p>
<p>i did it exactly same thing, but I was thinking that maybe
someone here did measurements on this very equipment and got the
parameter file. <br>
</p>
<p>However, I've got another question, this time about GSASII menus.
The instrument parameters that can be refined for typical XRD are
slightly different than these for synchrotron. E.g., for XRD we
can select the type of radiation, and for synchrotron the wave
length. Is there any way to change the parameters set, other than
removing the histogram and adding it again?</p>

You might try one of the generic parameter sets (press cancel at
the parameter dialog) or just start with peak fitting to get
parameters from the pattern you have, (see

Either way you will not be able to get useful information on size
and microstrain, but you can start without an instrument parameter
file.

<div class="">Dear all,<br class="">
<br class="">
My colleague got a pattern from a synchrotron 'BL02B2 —
SPring-8'. I tried to help him with the refinement;
however, it's my first attempt to fit synchrotron data
and we don't have the parameter file. The colleague
wrote an email to the operators, but we didn't get any
response. I'm wondering if anybody did some measurements
there and got the parameters? I will appreciate any
help.<br class="">
<br class="">
I post the link to the website of the synchrotron.<br
