摘要: Abstract A study of sub-microsecond high voltage pulse excited glow discharges in atmospheric helium is carried out here. The discharge generated between the powered copper electrode and ground covered with a ceramic sheet. electrical optical characteristics two events each terms current amplitude, duration, time instant at peak accumulated charge are investigated on duration magnitude. time-resolved imaging 5 ns exposure used to demonstration spatio-temporal evolution discharge. It found that first depends markedly magnitude space accumulation sheet surface plays an important role ignition second
