Cathode rays are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied...

hollow cathode effect allows electrical conduction at a lower voltage or with more current in a cold-cathode gas-discharge lamp when the cathode is a conductive...

A cold cathode is a cathode that is not electrically heated by a filament. A cathode may be considered "cold" if it emits more electrons than can be supplied...

Cathodic protection (CP; /kæˈθɒdɪk/ ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell...

using a cathode-ray tube as a receiver, the concept of using one as a transmitter was novel. The first cathode-ray tube to use a hot cathode was developed...

electronics, cathode bias, also known as self-bias, or automatic bias, is a technique used with vacuum tubes to make the direct current (dc) cathode voltage...
