X-Ray Science (GRS)
Gordon Research Seminar

Frontier Science with Forefront Synchrotrons and XFEL Sources

Dates

July 29-30, 2017

Location

Stonehill College
Easton, MA

Organizers

Chair:
Wonsuk Cha

Meeting Description

The Gordon Research Seminar on X-Ray Science is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas.

X-ray science has played a very important role in physics, chemistry, biology, materials science, and in many other fields. Because utilizing advanced light sources like synchrotrons and XFELs has enabled to open new science and the development of novel x-ray characterization methods, this meeting will focus on recent advances in x-ray science and techniques from advanced light sources covering imaging, ultrafast science, time-resolved x-ray characterization, and other new techniques.
