The Applied Electromagnetics Department aims to investigate novel concepts in rf accelerators, beam-wave interactions and rf technology from the single photon to the high-power regime. For example, in the high-power regime we develop high-gradient accelerators for both high-intensity and high-brightness beams for applications in High Energy Physics, medicine, ultrafast electron sources and x-ray light sources. At the other extreme of the single-photon regime, we are developing mm-wave qubits, quantum transducers, high Q resonators with custom developed superconducting materials, innovative designs and low noise measurements. We participate in the theoretical analysis, design ,fabrication and experimental verification of these devices. Our work is done in collaboration with universities, national laboratories and industries across the globe.
