\"\"This ampoule was especially made for\u00a0\u00a0experiments with high voltage.<\/p>\n

This tube does not contain any other “starter” gases, just pure Selenium. It needs a certain temperature to “ingnite”. Put the ampoule under boiling water to increase the pressure inside (Selenium even needs a bit more heat than others). Once illuminated with suitable electrodes, the ampoule keeps the ideal temperature for continuous illumination. It will work with a tesla tube only\u00a0 if heated enough before and during operation.<\/p>\n

On the main picture you see the illuminated ampoule. Connected to a 5000V\/35kHz transformer via two metal loops. The transformers can be found here.<\/a><\/p>\n

The tube contains sublimed selenium which evaporates during operation and keeps the necessary pressure to illuminate.<\/p>","protected":false},"excerpt":{"rendered":"
