are all - " long. larger and more intricate tubes were made, in sizes up to ", with the glass tube formed into all sorts of twists, bows and spiral shapes. the inverter modules for cold-cathode flourescent (ccfl) lcd panel backlights work very well for powering geissler tubes, although you shouldn't...
material and process technologies are common to the vacuum tube industry as a whole, which continues to serve many applications across a wide variety of industries. these include: lighting: incandescent, fluorescent, & high-power arc lamps communications: microwave, traveling wave, & high-power amplifier tubes...
gauge head to the readout. gauge heads are usually mounted vertically, i.e. with the connection downwards. this is to allow the gauge heads to read correctly and also to prevent debris from entering the head. for systems such as vacuum furnaces the high vacuum gauge most used is the penning cold cathode...
from the cathode. a device employing this latter method is known as a cold cathode device. in high voltage switching the presence of high voltages, and hence the possibility of large voltage gradients within devices means that the cold cathode system, quite a rarity in most other types of tubes, is...

and devices are vital tools, which link people and satellites in order to enable global communications. spaceborne tubes are the power generators for the transponders carried on satellites. they retransmit tv or telecommunication signals back to the ground. the electron tubes used for this application...
