- Work was presented at the SAS-2012 conference (www.sas2012.com). This include a summary of standardization in the canSAS session and a presentation on the latex round robin measurements.
Glassy Carbon Round Robin
Two samples of glassy carbons from Jan Ilavsky have been doing the rounds. They've been to NIST, ILL, ISIS, APS, ESRF and Diamond and ANSTO.
Details and data here : Glassy Carbon Round Robin
Polystyrene Latex Round Robin
Samples of a monodisperse polystyrene latex have recently been measured at ILL (D22 and D11), ANSTO (Quokka), ISIS (SANS2D) and at NCNR (NG7). Samples are also at Diamond awaiting measurement. Details and data here : Latex Round Robin
A new series of samples designated J, K, L and that have slightly different dilution have been provided for measurements at APS, FRMII, SPRING-8 and ILL.
We will try to gather summaries of the procedures used for calibration of small-angle scattering instruments. It has been suggested that summaries of information would benefit both users and those who run instruments and facilities. Everyone is encouraged to contribute to this work in progress. Procedures for laboratory instruments as well as sycnchrotron and neutron facilities are welcome.
