Collapse of electron plasma wave in microwave plasma interaction

Y Nishida, A Lee, N C Luhmann Jr, M Rhodes1990年Plasma Physics and Controlled FusionIF 2.2出版社

During the interaction of obliquely incident microwaves with an unmagnetized inhomogeneous laboratory plasma, the Langmuir wave energy is observed to narrow spatially and to rapidly grow to its peak value followed by a sudden collapse. This phenomenon has been referred to as the 'Soliton Flash' and occurs at rather high intensity microwave radiation (P0>or=600 W, eta 0=E02/8 pi n kappa T>or=4*10-3). The observed flash can be interpreted using the wavebreaking model, and the electric field strength at the wavebreaking time has been estimated by several methods, these methods showing reasonable agreement.

斜め入射マイクロ波と無磁化非一様プラズマとの相互作用において、ラングミュア波のエネルギーが空間的に収束し、急激にピーク値まで成長した後、突然崩壊することが観測された。この現象は「ソリトン・フラッシュ」と呼ばれ、比較的高強度のマイクロ波放射(P0>600W、η0=E02/8πnκT>4×10-3)において発生する。観測されたフラッシュは波動破砕モデルを用いて解釈することができ、波動破砕時における電場強度は複数の手法により推定され、それらの手法は合理的な一致を示した。
