RadiaBeam wins Phase II Small Business Innovation in Research (SBIR) award from the Department of Energy for an X-band traveling wave deflector. (Los Angeles, CA, 13JUL06) RadiaBeam Technologies, LLC has been awarded a Phase II continuation of its Department of Energy Small Business Innovation in Research (SBIR) project, entitled, "An X-band, Traveling Wave, Deflection Mode Cavity for Ultra-Fast Beam Manipulation and Diagnosis."
Under the grant, RadiaBeam will complete the development of a compact deflector cavity for beam longitudinal profiling and fast pulse switching. "This new deflecting cavity will become an indispensable tool for next-generation light sources and linear colliders" according to Salime Boucher, President of RadiaBeam Technologies. These types of accelerators, several of which are in construction and planning stages around the world, will require precise and fast diagnosis of the longitudinal profile with femtosecond resolution, explained Boucher.
The device works by creating a special radio-frequency mode in a cavity that transversely accelerates the electron beam in a time-dependent manner. For diagnostic purposes, this can be used to "sweep" the pulse of electrons, mapping the longitudinal distribution onto a transverse distribution. For high average current accelerators, the same cavity can be used to switch out a single pulse in a long pulse train for use elsewhere.
While deflecting cavities have been developed before, the innovation comes with the application of X-band RF power and a traveling wave structure. This makes the device much more compact and allows a faster sweeping and switching action.
RadiaBeam Technologies will work with UCLA's Particle Beam Physics Laboratory, headed by Professor James Rosenzweig, which has extensive experience in RF structure design and electron beam diagnosis. Dr. David Alesini, a highly respected expert in deflecting cavity design, will consult for the project. After the prototype has been fabricated and cold-tested in Los Angeles, the project will move to Brookhaven National Laboratory in New York. There, the deflecting cavity will be installed on the beamline of the Accelerator Test Facility, a facility renowned for its ultra-fast, high brightness beams. Using the planned high-power X-band infrastructure at the facility, it will be possible to perform extremely precise measurements of the longitudinal characteristics of the ATF beam.

About the SBIR Program
The SBIR program is a highly competitive grant system that encourages small business to explore their technological potential. SBIR funds the critical startup and development stages and it encourages the commercialization of the technology, product, or service, which, in turn, stimulates the U.S. economy. Since its enactment in 1982, as part of the Small Business Innovation Development Act, SBIR has helped thousands of small businesses to compete for federal research and development awards. In 2005, there were 1,555 applications submitted to the Department of Energy, of which 288 were granted.
