rf power in the lower-hybrid-frequency range is shown to produce plasma of density in the 10{sup 13} cm{sup {minus}3} range in the small toroidal heliac SHEILA by launching helicon waves. Measurements of wave dispersion and mode structure confirm that an {ital m}=1 helicon mode is launched inside the highly asymmetric plasma confined in the device. The suggestion that the main energy-transfer mechanism is by Landau damping is strongly supported by the experimental data.
