thyratron การใช้

• Thyratron dimmers were manufactured under license from Strand Electric of England.
• Other examples include the thyratron, krytron, sprytron, and ignitron tubes.
• The term " thyristor " was derived from a combination of " thyratron " and " transistor ".
• The cold cathode gives crossatron an advantage of achievable lifetime and reliability in comparison to a hydrogen-filled thyratron.
• However, switching service requiring voltages above 20 kV and involving very short risetimes remains within the domain of the thyratron.
• One miniature thyratron found an additional use as a noise source, when operated as a diode in a transverse magnetic field.
• Once turned on, the thyratron will remain on ( conducting ) as long as there is a significant current flowing through it.
• Input to the processors came from two sources, the shift registers from tape reading and the thyratron rings that emulated the wheels of the Tunny machine.
• In the time of SIGSALY, the transistor had not been developed and the digital sampling was done by circuits using the model 2051 Thyratron vacuum tube.
• He proposed a gyro to control the current to the electric motors on the stabilizer fins, with the actuating instructions being generated by thyratron vacuum tubes.
• In 1952, Jewell James Ebers from Bell Labs developed a prototype solid-state analog of thyratron  a four-layer transistor, or thyristor.
• DuMont was one of the earliest designers of the trigger sweep oscilloscope using a gas thyratron vacuum tube ( forerunner to the silicon controlled rectifier or SCR ).
• One miniature thyratron found an additional use as a noise source, when operated as a diode ( grid tied to cathode ) in a transverse magnetic field.
• Many types of cold-cathode switching tube were developed, including various types of thyratron, the krytron, cold cathode displays ( Nixie tube ) and others.
• This cell could be replaced by one thyratron with a load resistor and an input capacitor, but the operating frequency of such circuit did not exceed a few kHz.
• In 1932 Wynn-Williams published details of his thyratron-based scale-of-two counter, which allowed particles to be counted at much higher rates than previously.
• Like most linear beam tubes having external tuning cavities, IOTs are vulnerable to crowbar circuit based on a hydrogen thyratron or a triggered spark gap in the high-voltage supply.
• The gas in a thyratron is typically at a fraction of the pressure of air at sea level; 15 to 30 millibars ( 1.5 to 3 kPa ) is typical.
• A typical hot-cathode thyratron uses a heated filament cathode, completely contained within a shield assembly with a control grid on one open side, which faces the plate-shaped anode.
• Formerly, the mercury arc valve, the high-vacuum and gas-filled diode thermionic rectifiers, and triggered devices such as the thyratron and ignitron were widely used in power electronics.
