The Neon Demo - Bombarding

Bombarding is a very important part of processing the tube. As the tube is brought toward a vacuum, an intense voltage and current is applied to the remaining air. The air heats and 'purifies' the inside of the tubing. At still lower pressure levels, the electrical action 'activates' the electrodes. This process removes impurrities so that pure inert gas can be introduced.
