Q Standard Round Robin
This page is the working page for the Q Standard round robin.
- Joseph Kline (NIST - chair)
- Adrian Rennie (Uppsala University)
- Paul Butler (NIST - temporary?)
- Others TBA
- Shipping a valuable sample internationally without incurring taxes will require some careful planning/ thought. It may be easiest to ship back and forth from a central place (NIST seems the most natural in this case) rather than actually pass the same artifact around directly? Also arrange for return shipping as part of shipping?
- Need to develop protocol to send to each participant. How well the protocol works will help in refining the final protocol sent with the artifact. Protocol should probably include:
- calibrate instrument in usual way
- measuring a standard nanoparticle sample
- measuring the artifact using a rocking curve to ensure a proper measurement
- measuring the artifact rotating around the center point to get Qx and Qy on the detector
- position accuracy of 1mm is probably good enough
- rotational accuracy of 0.1 degrees is probably sufficient
- return measured pitch.
