1. A method for driving a gas electric discharge device having a first electrode and a second electrode for a gas electric discharge, which device is operable to produce a wall voltage between the first electrode and the second electrode, the method comprising:

  • applying a voltage, monotonously rising from a first set value to a second set value, between the first electrode and the second electrode thereby to generate a plurality of gas electric discharges so as to decrease the wall voltage for charge adjustment during the voltage rise, wherein;

    the first set value is set such that the sum of the first set value and the wall voltage at the beginning of applying the monotonously rising voltage is lower than or equal to a firing voltage, and the second set value is set such that the sum of the second set value and the wall voltage at the beginning of applying the monotonously rising voltage is higher than the firing voltage, and the rate of rise from the first voltage to the second voltage is a value within a range such that said plurality of gas electric discharges are generated as feeble electric discharges occurring intermittently and which do not reverse the polarity of the wall voltage.
