CHESS
FROM THE DIRECTOR
As winter winds down, I'm delighted that Operations have resumed and experimenters from all over the country are able to take advantage of the improved CESR beam stability, the new x-ray detectors, and the experimental station upgrades CHESS has been implementing over the past several months. The excitement on the experimental floor as users begin to see things they've "never been able to see before" is palpable. Over the next several months, CHESS will be working hard to make these new capabilities user friendly and to complete preparations for the transition to undulator operations during the summer down.

This issue of CHESS eNews highlights CHESS Project Scientist Peter Ko, tracing his path to becoming a synchrotron x-ray beam line scientist. CHESS is extremely proud of our legacy of training expert users, beam line scientists, and synchrotron leaders. Peter's story is an excellent example of what we mean by "hands-on" and "behind the shield wall" training.

The Xraise outreach team at CLASSE along with outreach staff from the Cornell Institute for Biology Teachers and the Boyce Thompson Institute traveled to Washington DC to participate in a workshop addressing the new Next Generation Science Standards (NGSS). The first workshop of its kind was hosted by the American Association for the Advancement of Science... more »
With a new deeper understanding for the complex interplay between chemistry and physics and what drives complex self-assembly researchers pave the way for new materials to enter many applications from fuel cells to circuits... more »
A video spotlighting MacCHESS, and some other work at CHESS, has been produced by WebsEdge. It was released at the February meeting of the Biophysical Society and is available to the public... more »
While he has never taken any formal courses in "synchrotron beamline science", Jun Young Peter Ko has worked on projects over the past 10 years that were clearly moving him towards expertise in the field. His current position at CHESS is "project scientist." Peter has played a key role in designing a new type of... more »
The CHESS Compact Undulator (CCU) program started several years ago with the development of Delta undulators for an ERL, culminating with performance tests of new undulators and x-ray optics this past Fall at A2. The program has matured over the last two years to the point where we are now... more »
New applications for ellipsoid shaped single-bounce capillaries extended the program this past year. In one case, CHESS capillaries, with working distances of 70 mm and 100 mm, were successfully used as a condensing optic with a zone-plate objective in a transmission X-ray microscope led by the APS Imaging Group and collaborator Francesco De Carlo.  In a second case... more »
Transverse or spatial coherence is one of the key metrics used to characterize the x-ray beams generated by 4th generation light sources. Full spatial coherence is highly sought after because as a light source approaches that level of perfection... more »
