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.

In this case, it’s a cold cathode audio visualizer, powered by fluorescent tubes doing unexpected things. The build details are a little scant, but we were able to coax an imgur album of [James ...

Some CT tubes are grid controlled for pulsed radiations to reduce the radiation dose. Field emission X-ray tubes (also called cold cathode tubes) In this style, in place of electron emission by ...

The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent streams of electricity travel from the bottom part of a glass tube to the top -- but no one ...

Cathodes emit electrons in sputtering systems, cathode ray tubes, and other vacuum tube systems ... cathodes used for field emission in vacuum tubes are called cold cathodes, whereas cathodes used as ...

Argonne develops a breakthrough material for the cathode in lithium-ion batteries. It enables an across-the-board improvement ...

In cold field emission electron microscopy ... SEM images are formed when the electron beam position on the sample surface is synchronized with the CRT, or cathode ray tube viewing screen. At each ...

Morgans' Scott Power said markets were suffering from US pre-election jitters not helped by mixed quarterly reporting season.

Cathode Ray Tube (CRT) televisions – those bulky relics ... Those of you that remember the warmth emanating from an old CRT set on cold winter nights can attest to their poor efficiency.

When you have a cold, inflammation and mucus can cause problems with the eustachian tube. This tube connects the middle ear (located behind the eardrum) to the back of the throat and nose.

Enjoy this list of the best local events and things to do this weekend in Cincinnati, Ohio. This list includes Christmas and holiday events, fun shows, tours, family friendly things to do, and more ...

Sturdy and reliable, the cold-cathode displays found their way into ... the foundation of the Space Race sported the venerable tubes. But time marches on, and a display that requires high voltage ...
