ON CERTAIN CONDITIONS FOR INCREASING THE BREAKDOWN STRENGTH OF VACUUMINSULATION

Experimental results on high-voltage nanosecond conditioning of all-me tal and film electrodes are presented. It is shown that the regime of treatment, at which the duration of high-voltage pulses acting on the electrodes of the vacuum gap equals the delay time of the breakdown in vacuum, is optimal for conditioning with electric pulses. Under optim al conditions, the conditioning efficiency rises with increasing pulse power.
