    Electron heating in a single - ended Q-machine was tried out by two different techniques: (1) by application of |i -wave power at the electron cyclotron frequency and (2) by insertion of a positively biased grid close to the hot plate. The electron temperature T was measured with a Langmuir probe. By means of the first method the electron temperature was increased by a factor of 2 without any significant disturbance of the ion distribution function. By the other method T was increased by a factor of 4. This heating was accompanied by a severe distortion of the ion distribution
