CHESS congratulates long-time user Professor Christopher K. Ober for winning two awards from the Society of Photopolymer Science and Technology – SPST: the Photopolymer Science and Technology Award (No.151100) and the Outstanding Achievement Award 2015 [1].

June will be a busy time as our annual CHESS User’s Meeting June 7th 2016 kicks off a series of six science workshops.

X-rays have long been the world-leading tool for crystallography, which allows researchers to make highly accurate atomic-scale maps of the perfect repeating structures that occur in crystals.

Hour of Code is a global movement that encourages students of all ages to try a one-hour introduction to computer science and the basics of coding through fun block tutorials.

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.

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.

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).
