==Q Standard Round Robin ==

This page is the working page for the Q Standard round robin.

* Joseph Kline (NIST - chair)

* Others TBA

==Planning Thoughts==
* 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.
