Abstract: It is found that our N equals 2, M equals 1 antenna can couple efficiently to the n equals 2, m equals 0 resonance surface as a result of toroidicity. This helps to deposit energy towards the centre of the discharge and the appearance of this surface in the plasma can be seen as a discontinuity on many of the macroscopic parameters. Without understanding the mechanism for the electron density increase it is difficult to explain the discontinuity except that it provides evidence of a connection between observed plasma behaviour and the Alfven wave spectrum.
