The CHESS monochromatic x-ray topography capability was reported on this summer at SRI-2015. The system (shown schematically right), typically available 6 weeks per year based on user demand at station C1, consists of a beam expanding monochromator, 6-circle diffractometer, and CHESS designed CMOS camera with real time sample-alignment capability.

Motivated to create a technology that could monitor, in real time, the full volumetric beam properties of an incident x-ray beam, a group of researchers from SUNY Stony Brook, Brookhaven National Laboratory and Case Western Reserve University have invented, fabricated and tested a new pixelated diamond x-ray beam “window” detector that could promise to revolutionize beamline design.

Over the past few years CHESS has implemented and continually improved a vertical beam position correction program to reduce beam motion throughout each run as the beam decays as well as from run to run (see related article).

The biology of human diseases and disorders is highly complex. In many cases, despite a great deal of detailed structural knowledge, understanding mechanisms is still a long way off.

Organic molecules are proving themselves attractive and promising alternatives for electrical energy storage applications. 

Now into the fourth year of its JunkGenies programming, Xraise is paving the way when it comes to infusing engineering design practices into science outreach.

Michelle Zhang, an undergraduate student in biological and environmental engineering, and a frequent user at the CHESS Sample Environment Lab, was part of the Cornell iGEM team in this year’s competition.

Station A2 this week is testing the boundaries of data acquisition, storage and retrieval here at the Cornell High Energy Synchrotron Source (CHESS) and the results are terabytes!
