Abstract :
The author presents results of optical and statistical studies of prebreakdown phenomena and electrical breakdown of n-hexane in a quasiuniform field of ~0.9-3.5 MV/cm (the duration of voltage exposure ranges from 20 ns to 2 μs) within gaps 25-150 μm in length. Boundaries for the realization of the mechanism of breakdown from cathode and anode depending on the field strength and distance between electrodes were defined. It is established that increase in breakdown field with reduction in gap length takes place in the case of the bubble breakdown mechanism from the cathode
