Frequency response of multipactor discharge
نویسنده
چکیده
This paper analyzes the frequency response of a two-surface multipactor in a rf circuit. An equation for the frequency band in which steady state multipactor can occur is derived in terms of the secondary emission properties of the surface, the quality factor Q of the rf circuit, and the operating voltage. The steady-state multipactor current is also derived, and is shown to be in excellent agreement with numerical computations that follow the temporal evolution of the multipactor discharge. © 1998 American Institute of Physics. @S1070-664X~98!00501-1#

Multipactor discharges are a resonant condition in which electrons impact a surface in phase with an alternating electric field. The discharge is sustained by electron multiplication from secondary emission. As motivation, multipactor discharges can adversely affect many different rf systems in vacuum, and this work provides an improved general understanding of multipactor and gives promising r...
متن کاملThe Coaxial Multipactor Experiment (CMX): A facility for investigating multipactor discharges
A multipactor discharge is a resonant condition for electrons in an alternating electric field. This discharge can be disruptive to radio frequency (RF) circuits, cavities, and resonators. The Coaxial Multipactor Experiment (CMX) investigates these discharges in parallel plate and coaxial transmission line geometries at frequencies from 40 to 150 MHz with goals of measuring the electron energy ...
متن کاملMultipactor discharge in a rectangular waveguide with regard to normal and tangential velocity components of secondary electrons
The distributions of normal and tangential components of secondary electron velocity are found from known experimental data. These distributions are used for calculation of position, width and relative intensity of multipactor discharges zones. The calculations are performed for the vacuum waveguide of the CESR RF system.

Multipactor discharges consists of electron multiplication between two surfaces by secondary electron emission in resonance with an alternating electric field. They are detrimental to the performance of radio frequency (RF) systems, such as the ICRF (ion cyclotron range of frequencies) antennas for heating of plasmas in the Alcator C-Mod tokamak and other nuclear fusion devices. This work inves...
متن کاملTemporal Evolution of Multipactor Discharge
Multipactor is an important resonant discharge phenomenon on which there have been surprisingly few publications in the open literature. Here, we extend the theoretical analysis of an idealized model. Emphases have been placed on the mutual interactions between the multipactor discharge and the rf. We show that the multipactor current may reach a very high level, transiently, before it settles ...
