Abstract:
A multistable device consisting of an emitter, an accelerating electrode and a collector, serving as the controlling element in conjunction with a control circuit, is used e.g. for the remote control of television receivers. The charge carriers as accelerated in the device, serve to supply atoms with excitation energy in the quantum-mechanical way by passing through various minimum and maximum speed values. From this, dynamic characteristics are obtained with multi-stable operating points. A closed control circuit is formed between the collector and the accelerating electrode, for causing stabilization at one of the possible voltage or current steps. Momentary variation of the accelerating voltage will effect the changing to different voltage or current steps.

The present invention relates to an electrode device for gas discharge sources, a gas discharge source comprising such an electrode device and to a method of operating the gas discharge source. The electrode device comprises an electrode wheel (1) rotatable around a rotational axis (3) and a wiper unit (11) arranged to limit the thickness of a liquid material film applied to at least a portion of an outer circumferential surface (18) of the electrode wheel (1) during rotation of said electrode wheel (1). The wiper unit (11) is arranged and designed to form a gap (17) between the outer circumferential surface (18) and a wiping edge (19) of the wiper unit (11) and to inhibit or at least reduce a migration of liquid material from side surfaces to the outer circumferential surface (18) of the electrode wheel (1) during rotation. With the proposed electrode device the electrode wheel (1) can be rotated at higher rotational speeds without the formation of droplets resulting in a higher output power and pulse frequency of a gas discharge source having such an electrode device.
