Claim 12:
13. A plasma control program which is a program used in a plasma control system including a high-frequency power supply, an antenna group comprising a plurality of antennas connected to the high-frequency power supply, a plurality of reactance variable elements connected to a feeding side and a ground side of the plurality of antennas constituting the antenna group, and a current detection mechanism that detects a current flowing through the feeding side and the ground side of the plurality of antennas constituting the antenna group,
wherein the program allows a computer to function as a uniformity calculation unit that calculates a uniformity index value of the current flowing through the plurality of antennas based on a current value detected by the current detection mechanism and a reactance changing unit that changes the reactances of the plurality of reactance variable elements in a predetermined order so that the uniformity index value calculated by the uniformity calculation unit approaches a predetermined set value.
