Open up an explorer window and go to the odin drive, as described above. Select the XRD_analysis_software folder. Double click on the relevant folder, and copy the relevant files to your computer, and start the installation (.exe) file.
For analysing XRD data in Topas, you will need to use a suitable emission profile (see for example here for explanation).
A while after the X-ray tube has been changed, some W contamination wavelengths will appear. Therefore we are regularly making new measurements from a LaB6 standard in order to have an up-to-date emission profile. This can be found on the odin-server, under "useful_documents\d8_davinci_1\Topas_Refinement_Details". Select the ".lam" file that has been made before your own measurements.
Here we are using a Ni-filter which removes the extra contamination wavelengths, such that we can use the prewritten pre-written emission profile "CuKa5.lam" that is included in the Topas installation directory ("C:\TOPAS5\Lam").
