thermionic

He was best known for his work on thermionic vacuum tubes.

The reactor type as also been used with thermionic converters.

In 1880 he discovers thermionic emission or the Edison effect.

In recent years technology development programs for solar-heated thermionic space power systems were conducted.

Thermionic currents can be increased by decreasing the work function.

This type of circuit was used for thermionic valve (tube) technology.

The heat causes thermionic emission of electrons into the vacuum.

The design had one to two thousand thermionic valves (vacuum tubes).

Details of the history, science and technology of thermionic energy conversion can be found in books on the subject.

Frederick Guthrie is the first to report observing thermionic emission.

The other relies on vacuum tubes and the principles of thermionic emission.

Additionally, the machine used 4,200 thermionic valves that had to be replaced constantly.

They used Thermionic valve and binary representation of numbers.

"First," he said, "do you know how a thermionic valve works ?"

It used thermionic valves (vacuum tubes) to implement the logic.

Thermionic emission can also be enhanced by interaction with other forms of excitation such as light.

It used Thermionic valve to implement switches, and decimal representation for numbers.

When hot, the filament releases electrons into the vacuum, a process called thermionic emission.

Thermionic emission can be used to measure the work function of both the hot emitter and cold collector.

Electron gun, used to generate electrons by way of thermionic or field emission from a source tip.

Voyager 2 uses three of these radioisotope thermionic generators.

This machine used thermionic valves to generate a clock frequency of 125 kHz.

In his doctoral thesis he described the noble gas filled thermionic converter developed by him.

Traditionally they have been used in fuel cells and other devices that convert chemical, nuclear, or thermionic energy to electricity.

Of course, the photoelectric effect may be used in the retarding mode, as with the thermionic apparatus described above.
