Prof. Dr. Luigi Palumbo graduated in electronic engineering from the University of Naples Federico II, Naples, Italy, in 1979. He started his career in the field of applied electromagnetism and particle accelerators at KFA, Jülich, Germany, CERN, Geneva, Switzerland, and Laboratori Nazionali di Frascati (Frascati), Istituto Nazionale di Fisica Nucleare (INFN), Frascati, Italy. He is currently a Full Professor in physics at the Sapienza University of Rome in Italy. He has been responsible for several projects concerning particle accelerators for basic science and their applications in medicine and industry. His main fields of activity include scattering of electromagnetic waves, beam–wall interaction in particle accelerators, coupling impedance and wakefields, RF and microwave devices for beam diagnostics and manipulation, space charge effects, single-bunch and multi-bunch instabilities, instability control active systems (feedbacks), and via Landau Camping, high-frequency RF devices design, high-brightness photoinjectors for free electron lasers, and laser–plasma interaction for proton sources.
