The generation of cobalt emitter for field ionization

Abstract EN

A new method for the preparation of cobalt dendrites on tungsten wires is described.

A simple drop cell is constructed.

DC pulses through the cell proved to be unsuitable for the production of cobalt dendritic surfaces.

Crystalline bobalt dendrites are obtained by using AC pulses.

The cobalt emitter is examined as a field anode in the field ionization source.
