摘要:
The invention relates to a cathode ray tube having an input resonator cavity which includes a first metal wall (2) and, spaced apart therefrom, a second metal wall (3) each conveying a low electric potential and constituting coupling areas (6, 7) at axially spaced locations, in which areas metal elements (10, 12) conveying a high electric potential are located opposite surface sections (8, 9 and 14, 15) which are electrically connected to the metal walls (2, 3) via insulating dielectrics (11, 13), the coupling areas (6, 7) being separated by a spacing dielectric. A high-voltage stable arrangement which is resistant to temperature fluctuations is obtained in that the spacing dielectric consists of a different material than the insulating dielectrics (6, 7) and has a lower value of the product of loss factor and dielectric constant (tg.delta..times..epsilon.) at a high frequency.

The magnetron is installed on the excitation cavity and connected to the excitation cavity, the excitation cavity is detachably connected to the load, the magnetron is provided with an injection antenna, and the injection antenna is used to receive an injected external signal and couple the injected external signal into the magnetron for realizing injection locking. The injected external signal is injected by a monopole antenna, and coupled into the magnetron resonant cavity through a magnetron filament, and the output microwave of the magnetron is output through the excitation cavity, and passes through the waveguide directional coupler, and is finally absorbed by the load, such that the output microwave of the magnetron can be locked by the injected external signal.

A multi-frequency klystron has an electron gun which generates a beam, a circuit of bunch-align-collect (BAC) tuned cavities that bunch the beam and amplify an RF signal, a collector where the beam is collected and dumped, and a standard output cavity and waveguide coupled to a window to output RF power at a fundamental mode to an external load. In addition, the klystron has additional bunch-align-collect (BAC) cavities tuned to a higher harmonic frequency, and a harmonic output cavity and waveguide coupled via a window to an additional external load.

摘要:
Tips of emitters are protruded over a control electrode in a field emission cathode. The cathode is a part of an input cavity, and an anode facing the cathode is also a part of the input cavity. A voltage which is in the vicinity of a threshold value or less than the threshold value is applied across the control electrode and the emitters, so that an emission current is modulated in density by a RF input signal.

An electron cyclotron resonance (ECR) plasma source for generating a plasma for etching, deposition, pre-deposition and material property modification processes. The plasma source includes two magnetic field sources. The first magnetic field source provides a magnetic field of sufficient intensity to achieve an ECR condition for a given microwave frequency input beam. The second magnetic field source enhances the uniformity of the plasma formed and the uniformity of the output by creating a uniform field region in the plasma generating chamber. The second magnetic field source also reduces the magnetic field so that the plasma near the extraction system and the output extracted are less magnetized. The magnetic field intensity, longitudinal position, radial position and pole orientation are design variables for adjusting the second magnetic field source to enhance uniformity and reduce the magnetization of the output.The ECR plasma source also includes a window apparatus which electrically isolates the plasma generating chamber which is at a high potential from the microwave source near ground potential. The window apparatus is cooled and also serves as a pressure isolator between the plasma generating chamber which is at vacuum pressure and the microwave source which is at atmospheric pressure.

A resonant cavity (49) which facilitates coupling to another resonant cavity includes walls (40, 42) and an electrically conducting mast (43). One of the walls (40) has a coupling orifice (41) for coupling the resonant cavity (49) to another resonant cavity. The electrically conducting mast (43) projects from the second wall (42) opposite the first wall (40) and faces the coupling orifice (41). The electrically conducting mast (43) terminates with a hook-shaped portion (44) which contacts an edge of the coupling orifice (41). The resonant cavity (49) is suited for applications requiring secondary output cavities coupled to inductive output tubes.
