Space charge effects for multipactor in coaxial lines

Michael Mattes, Francisco Edén Sorolla Rosario, Apostolos Sounas

Multipactor is a hazardous vacuum discharge produced by secondary electron emission within microwave devices of particle accelerators and telecommunication satellites. This work analyzes the dynamics of the multipactor discharge within a coaxial line for t ...

Microwave gas breakdown in elliptical waveguides

Michael Mattes, Francisco Edén Sorolla Rosario, Ioannis Koufogiannis

This paper analyzes the microwave gas discharge within elliptical waveguides excited by the fundamental mode. The Rayleigh-Ritz method has been applied to solve the continuity equation. The eigenvalue problem defined by the breakdown condition has been sol ...

Multipactor Analysis in Parallel-Plate Waveguides Loaded by a Single Dielectric Slab

Michael Mattes, Francisco Edén Sorolla Rosario, Apostolos Sounas

This paper studies the evolution of the multipactor discharge inside a parallel-plate waveguide partially loaded by a dielectric slab. The effect of static charges on the dielectric surface as well as of induced charges on the metallic plates are included. ...

Modeling microwave/electron-cloud interaction

Michael Mattes, Francisco Edén Sorolla Rosario, Frank Zimmermann

Starting from the separate codes BI-RME and ECLOUD or PyECLOUD, we are developing a novel joint simulation tool, which models the combined effect of a charged particle beam and of microwaves on an electron cloud. Possible applications include the degradati ...

Algorithm to calculate a large number of roots of the cross-product of Bessel functions

Juan Ramon Mosig, Michael Mattes, Francisco Edén Sorolla Rosario

This paper describes an algorithm to calculate a large number of roots of the cross-product of Bessel functions and of their first derivatives. The algorithm initially finds the roots of the zeroth order using an auxiliary function that exhibits the same r ...

Analyzing Corona breakdown with a finite element-based electromagnetic solver

Juan Ramon Mosig, Michael Mattes, Francisco Edén Sorolla Rosario, Ioannis Koufogiannis

This paper demonstrates how an already developed finite element code for solving electromagnetic problems can be manipulated and simply extended so as to investigate complicated corona breakdowns. A safe criterion based on the eigenvalue analysis is used i ...
