Numerical simulations of a new-type axial vircator with a reflector for enhanced efficiency
Résumé
Oral presentation. A new type of axial vircator with reflector is numerically simulated with a PIC code for the first time. The power conversion efficiency of classical vircator is shown to be enhanced from 1% to 4.8%. Optimization of both reflector position and radius is expected to increase performances. http://www.ece.unm.edu/summa/notes/AMEREM-EUROEM/EUROEM2012-final-10July2012NPA -SUMMA.pdf
