English: Diagram of a resonant cavity magnetron in SVG adapted from a PNG image by Ian Dunster 14:04, 14 November 2005 (UTC) from a diagram in Radar by T. J. Morgan - part of the The Mechanical Age Library - Muller - c1950 - No ISBN
The cavity magnetron is a high-power vacuum tube used in early radar systems and subsequently in microwave ovens and in linear particle accelerators. A cavity magnetron generates microwaves using the interaction of a stream of electrons with a magnetic field, while moving past a series of cavity resonators, which are small, open cavities in a ...
Engineering diagram of a four cavity coaxial gyroklystron at the University of Maryland, IREAP. The gyroklystron has cylindrical or coaxial cavities and operates with transverse electric field modes. Since the interaction depends on the resonance condition, larger cavity dimensions than a conventional klystron can be used.
The Weiss magneton was experimentally derived in 1911 as a unit of magnetic moment equal to 1.53 × 10 −24 joules per tesla, which is about 20% of the Bohr magneton. In the summer of 1913, the values for the natural units of atomic angular momentum and magnetic moment were obtained by the Danish physicist Niels Bohr as a consequence of his ...
The theoretical principles governing the operation of a maser were first described by Joseph Weber of the University of Maryland, College Park at the Electron Tube Research Conference in June 1952 in Ottawa, [2] with a summary published in the June 1953 Transactions of the Institute of Radio Engineers Professional Group on Electron Devices, [3] and simultaneously by Nikolay Basov and Alexander ...
Diagram of cyclotron operation from Lawrence's 1934 patent. ... In the magnetron, electrons are bent into a circular path by a magnetic field, ...
Researchers have developed an inexpensive blood test that they say can detect pancreatic cancer — even in its early stages.. Using a small blood sample, researchers from Oregon Health & Science ...
Magnetic field (green) induced by a current-carrying wire winding (red) in a magnetic circuit consisting of an iron core C forming a closed loop with two air gaps G in it. In an analogy to an electric circuit, the winding acts analogously to an electric battery, providing the magnetizing field , the core pieces act like wires, and the gaps G act like resistors.
