BSSergey Baryshev, Assistant Professor of Electrical and Computer Engineering, has received a prestigious Accelerator Stewardship award from the Office of High Energy Physics at the Department of Energy (DOE), to design and build a high power X-band nanosecond pulse microscopy system to study fundamental origins of vacuum breakdown. Congratulations!

Accelerator Stewardship works to make particle accelerator technology widely available to science and industry by supporting use-inspired basic research in accelerator science and technology (

Baryshev group of Michigan State University will collaborate with RF group of SLAC National Accelerator Laboratory and Argonne Wakefield Accelerator group of Argonne National Laboratory to develop a deeper understanding of physical origins of the vacuum breakdown/arc by testing the hot cathodic scenario of its formation. This work is to address the core challenges for future collider, high brightness X-ray source, and electron and proton therapy system technologies: to be energy efficient, cost effective and compact these systems must operate in X-band and be able to comprehend multi-megawatt input power (electric gradient >100 MV/m). Vacuum breakdown remains the major limiting factor slowing down the progress in this field: electrical breakdowns happen at the micro-scale but arrest operation of multi-kilometer facilities. Therefore, vacuum arc is studied with highest attention at CERN in the effort to increase the accelerator figure of merit called accelerating gradient, and minimize accelerator downtime.
This work is an extension of our prior findings described in detail in
