摘要： Disclosed are methods and devices suitable for generating electron beams and pulses of radiation. Specifically, in some disclosed embodiments, multiple emitting electrodes of a ferroelectric emitter are sequentially activated, generating a relatively long electron beam pulse that is substantially a series of substantially consecutive short electron beam pulses generated by the sequentially-activated individual emitting electrodes.

摘要： A stabilized high-voltage power supply is disclosed, having a general setup similar to a pulse-step modulator. The power supply comprises a plurality of DC power modules (40) having their outputs connected in a series configuration. Each power module comprises a DC voltage source (41), a DC-DC converter (42), and an output switching circuit (43). The total output voltage of the power supply is regulated by regulating the DC link voltage at the output of each power module. This is achieved by an appropriate feedback control circuit driving the DC-DC converter of each power module. In this manlier, low output ripple and a rapid response to changes in output current can be achieved. The power supply may be used, e.g., as the cathode power supply of a gyrotron.

摘要： An integrated high-frequency generator system utilizing the magnetic field of the target application including a magnetic resonance magnet having an application zone and a high-frequency (microwave/terahertz) generator zone in the magnetic field of the magnetic resonance magnet; and a high-frequency (microwave/terahertz) generator disposed in the high-frequency (microwave/terahertz) generator zone and utilizing the magnet field of the magnetic resonance magnet to generate the high-frequency (microwave/terahertz) radiation. The magnetic resonance magnet may have an auxiliary magnetic field source for modifying the magnetic field profile in the high-frequency (microwave/terahertz) generator zone. The high-frequency (microwave/terahertz) generator may include an electron gun for generating an electron beam adapted to be focused by a magnetic field source having a spatially rising region, a homogenous region and a decaying region, an interaction structure for generating high-frequency (microwave/terahertz) radiation, an internal mode converter in the homogenous region for extracting the high-frequency (microwave/terahertz) radiation through a window, and a reduced collector disposed substantially in the homogenous region before the electron beam spreads in the decaying region.

摘要： The present invention provides a multi-beam klystron apparatus. In the above-described multi-beam klystron apparatus, the magnetic field generating element of the electron-gun-unit-side magnetic field generating unit is disposed around the electron gun unit, and a plurality of magnetic gaps are provided in the inner peripheral surface of the magnetic pole, which covers the magnetic field generating element, in the direction of travel of the electron beams. Therefore, lines of magnetic force, which are parallel to the center axis of the radio-frequency interaction unit, can be generated. Thus, even the electron beam, which is generated from the location apart from the center axis of the electron gun unit, can be guided to the radio-frequency interaction unit in the same manner as in the location at the canter axis of the electron gun unit.
