Workshop 8

Thursday, May 4
Bldg. 402, Rm. E1100/E1200
8:30 am - 12:20 pm
1:15 pm - 5:00 pm, with beamline tours 5:00-6:00 pm

Inelastic X-ray Scattering: Present and Future at the APS

Organizers:
Esen Ercan Alp, Advanced Photon Source, Argonne National Laboratory
John Hill, Brookhaven National Laboratory
Steve Heald, PNC-CAT, Advanced Photon Source, Argonne National Laboratory
Guoyin Shen, HP-CAT, Advanced Photon Source, Argonne National Laboratory


This workshop will focus on various inelastic x-ray scattering (IXS) techniques currently practiced at the APS. There are now half a dozen beamlines with dedicated or semi-dedicated inelastic x-ray spectrometers, and our goal is to bring the science being done at these beamlines, as well as their new capabilities like the dedicated Sector 30 IXS-CDT beamline to the attention of the APS Users. Also, the workshops participants will have a chance to visit these beamlines and learn their capabilities and meet with the responsible scientists.
