Summary

The existing model of a collisionless alkali plasma diode is extended including the case of two incandescent plane electrodes emitting electrons as well as ions with half-Maxwellian velocity distributions. The potential distributions derived from this theory are examined in detail. Physically necessary conditions reduce the well-known ambiguity of solutions to a single one (wih uniform plasma potential) at a given set of parameters. Further solutions, corresponding to spatially oscillatory potential shapes which are consitent with the collisionless theory disappear if the ion-ion collision probability within the diode plasma exceeds 0.1 per emitter distance. In experiment the potential distributions are scanned using an electron beam probe technique. The results are consistent with theory. (auth)
