Head-tail modes for strong space charge
Physical Review Special Topics. Accelerators and Beams, 2009 The head-tail modes are described for the space charge tune shift significantly exceeding the synchrotron tune. A general equation for the modes is derived. The spatial shapes of the modes, their frequencies, and coherent growth rates are explored.

Space Charge Modulated Electrical Breakdown [PDF]
Scientific Reports, 2016 AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...
