  3. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television ...

  4. Sutton tube - Wikipedia

    en.wikipedia.org/wiki/Sutton_tube

    Sutton tube was the name given to the first reflex klystron, developed in 1940 by Robert W. Sutton of Signal School group at the Bristol University. The Sutton tube was developed as a local oscillator for the receiver of 10cm microwave radar sets. Due to its geometry and long drift space, it suffered from mode jumping through the tuning range.

  5. Twystron - Wikipedia

    en.wikipedia.org/wiki/Twystron

    The twystron amplifies a source signal using a conventional klystron, which consists of a series of cylindrical resonant chambers fed with the source signal. An electron gun at one end of the tube produces electrons that flow through holes in the centers of the resonators. As they pass through the holes, the signal within the resonator causes the electrons to "bunch up", a process known as ...

    There are 15 counties in the U.S. state of Arizona. [1] Four counties (Mohave, Pima, Yavapai and Yuma) were created in 1864 following the organization of the Arizona Territory in 1862. The now defunct Pah-Ute County was split from Mohave County in 1865, but merged back in 1871. All but La Paz County were created by the time Arizona was granted statehood in 1912. La Paz County was established ...

    en.wikipedia.org/wiki/List_of_counties_in_Oklahoma

    A few years after statehood, a constitutional amendment allowed them to be abolished on a county-by-county basis, and by the mid-1930s, all Oklahoma counties had voted to do so. [3] According to the Oklahoma Constitution, a county can be disorganized if the sum of all taxable property is less than $2.5 million.

  9. List of counties in Maryland - Wikipedia

    en.wikipedia.org/wiki/List_of_counties_in_Maryland

    Outside Baltimore (which is an independent city) the county is the default unit of local government. Under Maryland law, counties exercise powers reserved in most other states at the municipal or state levels, so there is little incentive for a community to incorporate. Many of the state's most populous and economically important communities, such as Bethesda, Silver Spring, Columbia, and ...
