How can I perform a phi scan on a Bruker Discover D8 machine?

In order to verify the epitaxial nature of the thin films, one can perform a phi scan. The distribution of a certain omega-2theta peak along phi will be indicative of the two-dimensional...

Why is my GIXRD data noisier than coupled scan data?

I have GaN and AlN films ranging from 10 nm-150 nm in thickness. For the thicker films, I can use the general theta-2theta coupled scan. But for the thinner films, I have to use the grazing...

How to convert a Bruker GADDS frame to a lossless image?

When using a two-dimensional detector, Bruker Discover machines can give a two-dimensional "GADDS Frame" that shows intensity as a function of 2theta and chi. Now the software does not have any...

Thank you guys. I forgot to mention that I had sent them a few emails without getting any answer. I'm not sure if anybody checks that account at all.

Be patient. The Lujan Center has other issues going on these days.
