STOCKHOLM, Sweden and KARLSRUHE, Germany – March 18, 2010 – Excillum and Bruker AXS today announced an exclusive collaboration to develop and market a unique new metal-jet X-ray source for X-ray diffraction applications. This novel source is the fruit of many years of research at the Royal Institute of Technology in Stockholm, Sweden. It is more than ten times brighter than the most powerful available laboratory sources. This unequalled brightness can greatly benefit any experiment that currently employs a rotating anode generator (RAG) source. Despite this unparalleled performance, the new source also features a cost of ownership which is very competitive with conventional RAG technology. Applications of interest include protein structure determination via X-ray crystallography, small angle X-ray scattering (SAXS and GI-SAXS) and all experiments where ultra-high X-ray flux on a small spot is essential.

Dr. Oscar Hemberg, CEO of Excillum, noted: "We are excited to work with Bruker AXS, a world leader in X-ray diffraction, to bring this new technology to the market. We believe the unprecedented brightness of this new source will allow researchers to bring many experiments, which previously could only be accomplished at a synchrotron beamline, into the home laboratory."

"We are looking forward to combining Excillum’s cutting-edge source technology with Bruker AXS’ comprehensive and best-in-class new product platform for X-ray diffraction," said Dr. Frank Burgaezy, Co-President of Bruker AXS. "This winning combination will open the doors to new laboratory applications for many researchers around the globe".
