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 by thermionic emission alone. It is used in gas-discharge lamps, such as neon lamps, discharge tubes, and some types of vacuum other type of cathode is a hot cathode, which is heated by electric current passing through a filament.

Additional Physical Format: Online version: Weston, G.F. (George Frederick). Cold cathode glow discharge tubes. London, Iliffe, (OCoLC)   Cold cathode glow discharge tubes are not new, they have evolved over the years from the early neon glow lamp, alongside the thermionic valve, to find application as indicators, voltage stabilisers, and as switches in low-current control circuits.

Introduction to Gas Discharge Tubes and Cold Cathode X-ray Tubes: Gas Discharge Tubes - The Basics. Prior to Roentgen’s discovery of x-rays inmany different types of gas discharge tubes were already in use (e.g., Geissler, Crookes, Hittorf, Lenard tubes).

A Nixie tube (English: / ˈ n ɪ k. s iː / NIK-see), or cold cathode display, is an electronic device for displaying numerals or other information using glow discharge.

Inside a Nixie tube The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols. The paper presents a heuristic model of cold cathode sputtering in glow discharges with a view to elucidating the underlying physics in the process.

Fig. 39 shows a typical volt–ampere characteristic of a cold-cathode discharge. Cold-cathode gas tubes may be divided into two categories, depending on the region of this characteristic in which they operate.

Glow discharge tubes require a drop of several hundred volts across the tube and operate in region II. The current is of the order of tens of milliamperes. The cold-cathode tubes used in advertising signs and hoardings are commonly called "neon tubes", although only the clear-glass red-light types actually contain neon.

The most widely-used fill gas is the same as in ordinary fluorescent and germicidal lamps, Hg in Ar, used either directly for its cyan colour (generally called "blue"); or used in. Cathode rays (electron beam or e-beam) are streams of electrons observed in discharge an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply).

They were first observed in by German. Encyclopedia article about cold-cathode discharge by The Free Dictionary. Principles of Electron Tubes Author: owski and Subject: DB-FP / Created Date: 10/6/ PM. A millimeter wave glow discharge detector biased to achieve an improvement in signal to noise ratio of about 20 dB.

The glow discharge detector tube comprises three or more electrodes, including an anode biased with respect to a cathode so as to generate a first discharge current which forms a high density plasma of electrons in a specific region of the tube, and a sensing electrode positioned Cited by: 1.

Cold Cathode Germicidal Ultraviolet Lamps, Tubes and Bulbs. STER-L-RAY ® Cold Cathode germicidal lamps are instant starting and utilize a large cylindrical cathode instead of a tungsten filament.

Due to this construction, the lamp is not adversely affected by frequent starting and the life is considerably in excess of other lamp types. Made of acrylic construction, these case lights features two (2) inch tubes, power inverter and an I/O header with power switch.

Tubes are clasified into 5 groups: (1) Ionization tubes, (2) Cold-cathode discharge tubes, (3) Hot-cathode arc discharge .The Townsend discharge is a gas ionization process where free electrons, accelerated by a sufficiently strong electric field, give rise to electrical conduction through a gas by avalanche multiplication caused by the ionization of molecules by ion impact.

When the number of free charges drops or the electric field weakens, the phenomenon ceases. The Townsend discharge is named after John.12" Cold Cathode Kit (Dual Ready) - Green 12" ultra bright cold cathode tube encased in its acrylic tube with ends sealed with rubber mounts for safety from breakage and aesthetics.
