The "XRD powder" is an Aeris Research edition benchtop X-ray diffractometer from Malvern Panalytical. It is meant for phase analysis of powders, is easy to use, and offers the option of making measurements while heating the sample in a N<sub><sub>2</sub></sub> atmosphere. The setup allows X-ray diffraction measurements with a Cu source in Bragg-Brentano mode (i.e., Theta-2Theta measurements where the incident and diffraction arms of the goniometer are coupled). We have a very limited selection of optics for this instrument, so there is little that the user can adjust.
The instrument has a 1D strip detector, which makes data acquisition very efficient, so you can measure your samples relatively quickly. The detector also has a fluorescence suppression option, so you can measure samples containing  for instance iron with the copper radiation.

==Software==
After making a measurement, you will need dedicated software for the data export and analysis.
 
====For data export====
On the Cleanroom drive you can find the DataViewer software, which is a very basic program that allows you to view your measurement results and export to other formats, e.g., csv or txt. To install DataViewer, go to the folder O:\CleanroomDrive\_Equipment\XRD Powder\XRD Aeris\XRDMP and click "setup" (XRDMP stands for XRD Measurement Program). This will open a menu that allows you to install both DataViewer and XRDMP Creator. Just choose to install DataViewer. XRDMP Creater is only needed if you have made an agreement with the equipment responsible that you are allowed to create your own measurement routines.


====For data analysis====
We have a license for the software "HighScore" for Rietveld refinement, allowing quantification of the phase composition. This is so far only available on the support computer by the instrument, but will become available on a remote computer.


====Additional software for measurements in a heated atmosphere====
==Process information==
If you are going to make measurements in a heated N<sub><sub>2</sub></sub> atmosphere, you will need the Nambicon software to control the heater. It is found in the folder O:\CleanroomDrive\_Equipment\XRD Powder\XRD Aeris\Anton Paar Nambicon.


==Measurements==
*Tips for choosing among the scan and hardware parameters including fluorescence suppression: [[/Measurement tips| XRD Powder measurement tips]]
This setup allows you to make X-ray diffraction measurements in Bragg-Brentano mode (i.e., Theta-2Theta measurements where the incident and diffraction arms of the goniometer are coupled).
We have a very limited selection of optics for this instrument, so there is little that the user can adjust.


It is possible to mount a special sample holder for heating the sample during the measurement. Please contact the equipment responsible to ask about this option.
*Malvern Panalytical has a large collection of webinars on XRD. You have to register to view them but the amount of email you receive afterwards is modest, so it's worth it in my opinion (Rebecca, July 2022). Some useful webinars include:

**A [https://www.malvernpanalytical.com/en/learn/events-and-training/webinars/W20210330XRD.html beginner’s tutorial] which also mentions sample preparation about half-way through and explains very briefly some of the issues that can arise from displaced samples, not having a thick enough sample layer, odd sized sample particles, etc.

The XRD Powder setup

The XRD Powder located in the basement of building 346 at Nanolab, Room 904.

The "XRD powder" is an Aeris Research edition benchtop X-ray diffractometer from Malvern Panalytical. It is meant for phase analysis of powders, is easy to use, and offers the option of making measurements while heating the sample in a N2 atmosphere. The setup allows X-ray diffraction measurements with a Cu source in Bragg-Brentano mode (i.e., Theta-2Theta measurements where the incident and diffraction arms of the goniometer are coupled). We have a very limited selection of optics for this instrument, so there is little that the user can adjust. The instrument has a 1D strip detector, which makes data acquisition very efficient, so you can measure your samples relatively quickly. The detector also has a fluorescence suppression option, so you can measure samples containing for instance iron with the copper radiation.

Please contact the equipment responsible if you would like to mount the special sample holder for heating during the measurement.
