Journal ArticleDOI
The role of outgassing in surface flashover under vacuum
TL;DR: In this article, the authors used high-speed electrical and optical diagnostics as a basis to discuss a new surface flashover model, where outgassing, caused by electron stimulated desorption, played a crucial role in the temporal flashover development.
Journal ArticleDOI
Plasma structures observed in gas breakdown using a 1.5 MW, 110 GHz pulsed gyrotron
Y. Hidaka,EunMi Choi,Ivan Mastovsky,Michael Shapiro,Jagadishwar R. Sirigiri,Richard J. Temkin,G. Edmiston,Andreas A. Neuber,Yasuhisa Oda +8 more
TL;DR: In this paper, a 2D plasma filamentary array was observed in gas breakdown experiments using a pulsed 1.5 MW, 110 GHz gyrotron Gaussian output beam with an intensity of up to 4MW/cm2.
Journal ArticleDOI
Initiation of high power microwave dielectric interface breakdown
TL;DR: In this paper, a simple model of vacuum/dielectric/vacuum interface breakdown initiation caused by high power microwave has been developed, where a spatially varying electron density normal to the interface surface has been introduced.
Journal ArticleDOI
Window breakdown caused by high-power microwaves
TL;DR: In this article, the authors investigated the physical mechanisms leading to microwave breakdown on windows for power levels on the order of 100 MW at 2.85 GHz using a 3-MW magnetron coupled to an S-band traveling wave resonator.
Journal ArticleDOI
Microbubble-based model analysis of liquid breakdown initiation by a submicrosecond pulse
J. Qian,Ravindra P. Joshi,Juergen F. Kolb,Karl H. Schoenbach,James C. Dickens,Andreas A. Neuber,M. Butcher,M. Cevallos,H.G. Krompholz,Edl Schamiloglu,John A. Gaudet +10 more
TL;DR: In this article, an electrical breakdown model for liquids in response to a submicrosecond (∼100ns) voltage pulse is presented, and quantitative evaluations carried out, and two-dimensional, time-dependent simulations have been carried out based on a continuum model for water, though the results are quite general.
