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 ...

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 ...

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.

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 ...

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.

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 ...

A neon tube is a sealed glass tube with a metal electrode at each end. When a high voltage current is applied to the electrodes the gas ionizes, causing it to emit colored light. “That red ...

(SOUNDBITE OF MACHINERY HUMMING) SWARTSELL: Back at the shop in Cincinnati, Wartman is finishing up his neon clock face. WARTMAN: Once we vacuum all the air out of the tube, we put the gas in ...

Alabama cities may not have the glitz and glare of Times Square or Las Vegas but that doesn’t mean we can’t rock a cool neon sign when one is called for. Some in Alabama are easily ...
