A device for generating an alkali plasma in thermodynamic equilibrium is described. It consists of a cylindrical tantalum cavity which is made incandescent by means of electron bombardment. The plasma obtained by contact ionization on the walls has a

Calculations have been made which refer to the effect of an azimuthal magnetic field on the limiting current in the low-pressure mercury arc. Measurements of the limiting current have been made using two discharge tubes, one of which contains a wire

An experiment on ionic waves sustained by collective amplification in a uniform, steady plasma, free of electric field, is described. The plasma is obtained by contact ionization of caesium or potassium vapours on the surface of two coaxial tantalum

A criterion for sheath formation is presented which allows for the effect of a weak magnetic field. Relevant measurements have been made using a low pressure mercury are in which an azimuthal or « pinch-type » magnetic field could be applied.

The effect of a sinusoidal signal of large amplitude on the characteristic of a Langmuir probe is studied. The average values of the current collected by the probe are calculated and measured. Results are in agreement with the theory in a region near

The electron temperature of a large diameter (8 cm)Q machine has been increased by a factor of 3 by electron cyclotron resonance heating. Using this technique we have eperimentally studied the effect of electron temperature on coherent flute modes dr

The results of an experimental study of alkali plasmas contained in a microwave resonator are described. The plasma, produced by thermal ionization in an incandescent cavity operating also as a microwave resonator, is steady and uniform. It is observ
