Abstract: | Experimental measurements were made of the ion energy cost η as a function of the parameters of a combined rf inductive-capacitive discharge at low pressures (p<10−2 Torr). It was established that η does not depend on the power supplied, it has a minimum as a function of pressure, and also decreases when an rf potential
is applied to the electrodes. The results can be used to find the optimum parameters in terms of energy efficiency of ion
formation and may be useful for refining the theoretical models of a combined rf inductive-capacitive discharge.
