The decay of space charge in a glassy epoxy resin following voltage removal [PDF]
, 2006 The PEA technique is used to measure the distribution of space charge in an epoxy resin after polarisation for one week at an applied field of 7.14kV/mm over a range of temperatures.

rf barrier compression with space charge
Physical Review Special Topics. Accelerators and Beams, 2010 Because of the long synchrotron period between the two barriers, bunch compression in a barrier bucket is usually relatively slow. The conservation of the phase space area requires that the compression is performed adiabatically, that is much slower than

Space charge behaviors in cable insulation under a direct current‐superimposed pulsed electric field
High Voltage, 2021 When high‐voltage direct current (HVDC) cables are subjected to a direct current(DC)‐superimposed pulsed electric stress, the pulsed voltage applied facilitates electrical tree generation and breakdown; however, the mechanism involved remains unclear. To

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.
