SPECTRA OF LOWER HYBRID WAVES REQUIRED TO SUSTAIN SIGNIFICANT CURRENTS
A simple quasi-linear model is used to compute the current that can be sustained by a power source with the spectrum of a given shape. It is shown (a) that the current observed in PETULA-B can be explained by theoretically determined broad spectra, and (b) that narrower spectra (with which it is impossible to sustain a significant current) can be made very efficient by minute modifications. A high N// wing, containing only a few per cent of the total power, is sufficient to increase the current generated by a few orders of magnitude. This current is of the same order as that obtained with a broad spectrum.
