As of October 2014, the three CHESS experimental stations known as G-line joined A1 and A2 in becoming among the first undulator-fed beam lines at CHESS. Thanks to a little luck and a lot of clever engineering... more »

The CHESS West wiggler source was removed over the summer. In its place are two custom 1.5m CHESS Compact Undulators which now feed the A-line/G-line endstations... more »

For most of CHESS's history, it was not possible to use undulator insertion devices. The reason for this was that in order to counter-rotate electrons and positrons in the same storage ring there had to be a "pretzel" orbit that caused the two particle beams... more »

A Pilatus3 6M pixel array detector has replaced the Q-210 CCD detector in the A1 hutch. This is the preferred detector worldwide for macromolecular crystallography, because of its large dynamic range, zero background, very small point spread function, and millisecond readout time... more »

The CHESS A-Line controls and safety systems have been upgraded to a modern PLC based system. The old relay and L.E.D. system has been replaced with a hybrid system that... more »

Starting last October, the CLASSE IT group has been commissioning a new data acquisition network with high-speed low-latency connections from the CHESS beamlines to over 130 terabytes of redundant disk arrays dedicated to the storage of CHESS x-ray data... more »
