Abstract

Using experimental measurements and theoretical analysis, it is shown that the HF/ELF conversion efficiency is controlled by the timescale for electron temperature saturation. This is a function of the ERP and frequency of the heater and the ionospheric electron density profile. For the current HAARP parameters, this corresponds to frequencies between 2 and 4 kHz. Efficiency optimization techniques as applied to the projected upgrading of the HAARP heater to its design power of 3.6 MW are discussed.
