Simulations of a Multipactor-Inhibited Waveguide Geometry

نویسنده

  • Eric Chojnacki
چکیده

Studies of multipactor resonances in coaxial and hollow waveguide via standard particle trajectory and secondary emission numerical simulation techniques are presented. Agreement between simulations and experimentally observed multipactor barriers gives confidence in results of simulation studies of a wedgeshaped hollow waveguide geometry that shows promise of being far less susceptible to multipactor resonances than standard coax and hollow rectangular waveguides. PACS Codes: 52.80.Vp, 52.80.Pi, 52.20.Dq

Multipactor 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.

Anti-multipactor TiN coating of RF power coupler components for TESLA at DESY

A development project was carried out at DESY, aimed at reducing secondary electron emission and multipactor effects in TESLA couplers by TiN layers generation on surfaces which were not protected in this way previously. Thin TiN films on ceramic or metallic surfaces were produced by deposition from Ti vapor in low pressure ammonia. Selection of processing parameters and their effect on multipa...

Multipactor in Minimum Electric Field Regions of Transmission Lines and Superconducting Rf Cavities*

Multipactor in beam-pipe transitions of superconducting RF cavities can be explained using RF potential well theory [1]. In this paper we present simulation results supporting this explanation for both RF cavities and transmission lines. INTRODUCTION Curved-shaped transition regions between a cavity and a beam pipe were thought to be multipactor-free. Thus recent experimental observations of mu...

Simulation of Multipactor Effect through the Individual Simulation of Electrons

In the context of the ESA Program AO 4025 Surface Treatment and Coating, we have developed a simulator called MEST for the prediction of the multipactor effect. The simulator has been developed using a micro level object-oriented approach, where each electron in the simulation is an independent object. This approach differs from other models described in the literature, which are macro level or...
