Issue No. 34
From the Director
The past month has been a blur of activity. After years of planning and preparation, the CLEO detector has been disassembled and removed from CESR. The article on the removal has links to extraordinary time-lapse photo sequences of CLEO being taken apart, piece by 30 ton piece. During the next few weeks, we will be installing a floor over the CLEO pit, reassembling CESR, and starting up for user operations. Removing CLEO is a major milestone in the preparations for CHESS-U.
At the same time, we've been very busy working with the international user community to prepare the science case for operating a 3rd generation, high-energy, high-flux synchrotron called "New Science Made Possible by CHESS-U." The scientific themes were identified during the series of science workshops held in June 2016. This has been a real community effort and CHESS thanks everyone for their input and hard work.
And, CHESS-U has begun in earnest. We've designed and prototyped the dual function magnets and are beginning procurement of long lead-time accelerator components. The x-ray beamline design is in the conceptual phase. We're planning on an external design review for the beamlines in December and beginning procurement of long lead-time x-ray components early in 2017.
Stay tuned for updates!
