GENERAL GOAL: Investigation of particle and photon beams and their mutual interactions with the goal of developing novel high-performance accelerators and radiation devices.

RECENT RESEARCH TOPICS: Study of electron-radiation beam interaction, providing pioneering analysis of the high-gain free-electron laser principles. Pioneering contributions to particle beam re-partitioning techniques in transverse-to-transverse and transverse-to-longitudinal phase space. Study of muon beam cooling schemes and ionization cooling theory. Development of a Smith-Purcell backward wave oscillator making use of an electron microscope towards a table-top terahertz generator. Pioneering study of fully coherent x-ray free-electron laser oscillator (XFELO) towards drastic improvement of the coherence and brightness beyond the current, self-amplified spontaneous emission based XFELs. Invention of four-crystal configuration of an x-ray cavity for tunable XFELO. Pushing the state-of-the-art in the x-ray optics technology necessary for an XFELO, including defect-free diamond crystals and ultralow-emittance electron injector .
