VORPAL網絡研討會--微放電/二次電子倍增模擬

主題: Modeling Multipacting Phenomena with the VORPAL code
主辦: Tech-X Corporation
時間: Thursday,January26,2012,2:00 PM EDT/11:00AM PT/19:00 GMT(Duration: 1 hour)
主講: Dr. Chet Nieter
Dr. Chet Nieter received his PhD from the University of Colorado in 1999.  He has been a Research Scientist with Tech-X Corporation since 2003, where he leads the effort in multipacting simulation for industrial applications.
內容:Multipacting is the resonance generation of electrons produced by electrons accelerated into a solid surface by oscillating electromagnetic fields.  In some situations, this resonant generation can grow exponentially, absorbing power and significantly modifying the applied fields.  This can lead to hard limitations on the power transmitted in rf devices.  In this webinar, we show how VORPAL can help engineers and researchers understand and mitigate multipacting in real rf systems.  We will show how to import a complex geometry (for instance, from CAD) into VORPAL and use VORPAL to find the multipacting resonances of that geometry.
