+X-ray absorption spectroscopy is a core technique of the DOE
+synchrotron user facilities and attracts diverse scientific
+communities. This 3-day course offered by NSLS-II experts introduced
+XAS data analysis to new and prospective users and provide an
+opportunity to perform real experiments at NSLS-II XAS beamlines. The
+first two days were devoted to the fundamentals of XAS analysis, data
+reduction and processing, and the basics of XAS experiments and
+instrumentation.
+
+Participants were trained on XAS data analysis of increasing
+complexity.  Modern XAS methods such as high-resolution spectroscopy
+were be introduced. On the third day, the participants participated in
+the experiments at XAS beamlines and analyzed the data they collected.

+This course was organized and presented by Lu Ma, Bruce Ravel, and Eli
+Stavitski with additional lectures by Denis Leshchev and Akhil Tayal
+and help from Dali Yang.  We are grateful to Kerri Banaszek for
+logistical support.

+---------------------
+
+:Sample preparation and sample environments:
+
+   A discussion of how to plan for your XAS experiment, how to prepare
+   your samples for measurement, and how to plan for *in situ* and
+   *operando* experiments

+
+:EXAFS analysis II:
+
+   The FeS\ :sub:`2` example from the previous day might seem a bit
+   too simple.  It involves analysis of a crystalline material, thus
+   the path through the analysis obviously starts with crystal data.
+   In these two lectures, some ideas are presented about how to
+   perform EXAFS analysis on more complex materials.

+
+Data from BMM
+~~~~~~~~~~~~~
+
+During the hands-on experiment at BMM in the morning, we measured
+several Mn standards along with the mineral `babingtonite
+<https://en.wikipedia.org/wiki/Babingtonite>`__ in fluorescence at the
+Mn and Fe edges.
+
+In the afternoon, we measured several Zn standards along with the
+mineral `petedunnite <http://webmineral.com/data/Petedunnite.shtml>`__
+in fluorescence at the Zn and Fe edges.
