"Coherent synchrotron radiation from storage rings as a broadband, high-power terahertz source''

Coherent synchrotron radiation (CSR) is a fascinating phenomenon recently observed in electron storage rings and shows promise as a broadband source of terahertz (THz) radiation with average powers at the kilowatt levels. The ring source of CSR also has several other unique characteristics such as high repetition rate, stability, synchronization with x-rays, and shaping the electric field pulse. I will discuss the science potential of high-power THz sources, and the experiments to date detailing CSR THz production. I will conclude with what a storage ring optimized for coherent THz radiation would require.

Refreshments will be served in CP 179 at 3:15 PM
