Accuracy in Powder Diffraction IV


Logo of the Accuracy in Powder Diffraction meetingWe are pleased to announce the location and dates for our next "Accuracy in Powder Diffraction" meeting. This meeting, designated APD-IV, is the fourth in the series which are held approximately every ten years. They constitute a review of the state of the art in powder diffraction techniques, instrumentation and data analysis methods. The meeting will host a program of invited presentations plus a contributed poster session. APD-IV will cover the broad range of developments in powder diffraction metrology and methodology in the time since APD-III. In addition, we will host an exhibition area where leading instrument manufacturers and providers will be available to discuss recent commercial developments in the diffraction context.

Proposed Format: Four days of a single-session symposium with various oral speakers.

Participants: Members of academia, industry, and government with interests in the Accuracy of Powder Diffraction.


The organizers invite contributed posters that also address issues of accuracy in powder diffraction measurements. The posters should be prepared in A0 format, portrait orientation. Download the abstract template (Word doc). Abstracts should be sent to Jim Cline and Ian Madsen: james.cline@nist.gov and Ian.Madsen@csiro.au. Abstracts are due by April 1st, 2013.

Conference Reception: 

The Smithsonian Natural History Museum’s Department of Mineral Sciences invites conference attendees to an open house with snacks and beverages.  The evening will be hosted by Smithsonian scientists who will share their research and show off their collections. Enjoy a rare and exclusive opportunity to go behind the scenes to tour the meteorite and gem and mineral collections, including the fabled "Blue room". Attendees will also be invited to explore the Museum's public Geology, Gem, and Mineral exhibition galleries.
