A two-dimensional, variable-separation model of the plasma dynamics inside a cylin- drical chamber with an axial magnetic eld is derived. The energy absorbed from an helicon-wave ionizes the injected gas and heats the plasma. The magnetic eld is found to provide a good radial con nement of the plasma leading to negligible current and power losses to the lateral wall. An eciency study aimed at a thruster application of the device is carried out, in terms of magnetic eld, absorbed power, and injected ow. Losses to the rear-wall are a serious concern in the selected con guration, leading to a fall of internal eciency, i.e. the ratio of plasma-beam power at the chamber exit to absorbed power, to values below a 40%
