The photo (above) shows a gas discharge sign designed by Sam Sampere of Syracuse University. This sign incorporates a neon discharge tube (the orange word "Physics") and mercury discharge tubes ...

These were the first gas discharge tubes and were mass-produced mainly for entertainment purposes. The neon tube, as we know it, was developed by a French engineer, Georges Claude in 1910 ...

that if a condenser of the order of a microfarad capacity was discharged through a tube containing neon at a pressure ... change in the character of the discharge, distinguishing clearly the ...

Why a gas-discharge tube is an important component for overvoltage ... the inert gas in the GDT (such as neon or argon) becomes fully ionized and no longer functions as an insulator.

After heating the tube with electricity to about 450 degrees Fahrenheit and blasting it free of impurities, Weido switches on the gas, unleashing a stream of neon that gradually fills the glass.

Subsequent researchers experimented with gases like carbon dioxide and nitrogen to make various types of vapor lamps, electric discharge ... with neon as the filler gas for a tube around 1902.

The gas in the tube is stimulated, by an electrical discharge in the case of a helium-neon laser, and the stimulated photons bounce back and forth between the mirrors until some finally blast out ...

Around 250 vintage signs fill the outdoor “boneyard” at the Neon Museum Las ... in a sealed glass tube that held a noble gas, resulting in a “glow discharge.” By shaping the tubes glass ...
