Crossed field device. It is a so-called Velocity-modulated Tube .

Crossed field device. A crossed field device, such as a magnetron or crossed field amplifier, that includes a cathode, an anode, one or more magnetic elements, and one or more extraction elements. And is also known as a crossed-field device. . It is basically considered as a self-excited microwave oscillator. A crossed field refers to a configuration in a mass spectrometer where electric and magnetic fields intersect, allowing for the generation of a toroidal electric field while ions are subjected to a homogeneous magnetic field. A control electrode positioned generally at a drift region away from the crossed-field amplification region Theoretical studies have been made on the nonlinear operating regimes of crossed-field vacuum devices, in the nonrelativistic regime. Ions are confined in orbits around a high-voltage cathode with co-rotating electrons confined by a relatively Definition: A magnetron is a device that generates high power electromagnetic wave. The theory is based on two elementary modes: a DC average background mode and an RF In another embodiment, the crossed field device includes an oval-shaped cathode and anode that are radially spaced from one another such that the device produces a radial electric (E) field and an axial magnetic (B) field. This setup facilitates electric mass scanning and mass determination. A crossed-field device such as a crossed-field amplifier or magnetron has a generally peripheral cathode body portion and an anode which cooperates with a crossed magnetic field to maintain emitted electrons on cycloidal and amplify an rf input signal as it travels to an rf outlet. Jan 16, 2024 · A Crossed Field Amplifier or CFA is a broadband microwave amplifier that utilizes the principles of magnetron and traveling wave tube (TWT) systems to amplify or increase the magnitude of the radio frequency (RF) input signal and deliver the amplified signal to the output port. The main interaction is a wave-particle interaction between those drifting electrons whose velocities match the phase velocity of the RF wave in the slow-wave structure. The CFA is similar in operation to the magnetron and is capable of providing relatively large amounts of power with high efficiency. It is a so-called Velocity-modulated Tube . The Crossed-Field Amplifier (CFA), is a broadband microwave amplifier that can also be used as an oscillator (Stabilotron). The Orbitron is a crossed-field device combining aspects of magnetic mirrors, magnetrons, and orbital ion traps. Apr 27, 2018 · The crossed-field amplifier (CFA) resembles a magnetron in which the ends of the slow-wave structure are connected to external waveguides so that broad-band operation is possible.

Explore the pros and cons of Crossed Field Amplifiers (CFAs), including their high efficiency and wide bandwidth, alongside limitations like low gain and high noise output. CFAs have been built with injected beams, with emission from the cathode (sole) and with both forward-wave and backward wave structures. A crossed-field amplifier (CFA) is a specialized vacuum tube, first introduced in the mid-1950s and frequently used as a microwave amplifier in very-high-power transmitters. ilht3v 0urt0 2blf y2da7 si rgucvpf trhwrs p0vdm 76rji fq
