Query: Study on the atmospheric pressure homogeneous discharge in air assisted
  with a floating carbon fibre microelectrode   Based on the consideration of increasing the number of initial electrons and
providing an appropriate distribution of electric field strength for discharge
space, a method of adopting the wire-cylindrical type electrode structure with
a floating carbon fibre electrode to achieve atmospheric pressure homogeneous
discharge (APHD) in air is proposed in this paper. Studies of the electrode
characteristics show that this structure can make full use of the
microdischarge process of the carbon fibre microelectrode and the good
discharge effect of the helical electrode to provide plenty of initial
electrons for the discharge space. Besides, the non-uniform electric field
distribution with gradual change is conducive to the slow growth of electron
avalanches in this structure. Thus, the initial discharge voltage can be
reduced and the formation of filamentary discharge channels can be inhibited,
which provides theoretical possibilities for the homogeneous discharge in
atmospheric air. Experiments show that a three-dimensional uniform discharge
phenomenon can be realized under a 6.0 kV applied voltage in a PFA tube of 6 mm
inner diameter, displaying good uniformity and large scale.
