In some cases, the spark gap needs to be irradiated with ultraviolet light or X-rays sources in order to obtain consistent values for smaller sphere gaps, with the gap spacing less than 1 cm [ 3, 4 ]. An abnormal phenomenon was observed that the breakdown voltage increased in a highly non-uniform electric field with the same gap distance. The Townsend theory breakdown criterion can be expressed as: where is the ionization coefficient, is the SEE coefficient, and d is the gas-gap distance. Sale Sold out.

In most cases involving In this paper we present results on sphere-plane and cylindrical rod-plane gaps in LN2 as a function of, We develop a criterion for spark breakdown in non-uniform field geometries with positive polarity and small electrode separations so that breakdown evolves without the formation of a leader. Irrespective of the polarity of the voltage applied, the field of either electrode on which fields are concentrated initiates breakdown. The breakdown conditions can be, respectively, evaluated by the streamer inception criterion and a fitting formula when the value of the geometric parameter is on opposite sides of a critical value.
