Description
| - In this paper, the current stability analysis was performed on the cold-emission cathode covered by a thin epoxy film. Non-destructive spectroscopic method, which is based on measuring current fluctuations, has been used to determine cathodes quality, which directly influents the stability of the emission current. Our investigations have been performed on tungsten cathodes with extra-sharp nanotip, operating under the HV (high-vacuum)conditions, usually in vacuums of 10-5 Pa order. All the cathodes used for this experiment have been prepared in our lab by improved electrochemical etching method, which is based on the presence of increased surface tension allowing reaching the geometrically precise shape of the cathode tip. After the two phase etching method, the tip was cleared and covered by thin epoxy film, which prevents the tip to be destroyed by ion bombardment that is caused by ions attracted back on to the cathode surface. A comprehensive investigation was carried out to determine particular no
