A cold cathode is a cathode in a gas-filled electron tube that is not heated by a filament. The voltage potential within the tube is sufficient to ionize the gas and cause the current to flow. For ...

A 4-pin plastic base with glass T-shaped envelope. Radiation symbol stamped on envelope. Donor’s card reads: “Cold cathode tube made by Western Electric for use in modern [about 1962] telephone ...

Old is new again as tiny mechanical contactors outperform solid-state switches, monolithic inductors for power conversion, ...

Hey, I'm considering getting a UV cold cathode for my windowed case, and I'm a little concerned for my eyes. Will the UV tube damage my eyes in any way? I've seen those sunglasses with the UV ...

IN the carbon- and tungsten-arc the electrons are in most cases emitted thermionically by the cathode, while in the mercury-arc (with mercury cathode) the cathode current is assumed to be due to the ...

WHEN a cold-cathode arc is initiated in the presence of a transverse magnetic field, movement of the cathode root occurs in a direction mutually perpendicular to the arc current axis and the magnetic ...

Hi, I bought a pair of these lights for PC's which are supposedly cold cathode tubes (in a funky blue colour).<BR>What I am noticing is that when the CPU is fairly busy, the lights flicker a bit. Its ...
