Intense intermittent radiation at the plasma frequency on EAST

Intense intermittent radiation has been observed regularly in EAST plasmas. The duration of radiation bursts is with a characterization time of a few microseconds. The radiation is very intense, with an equivalent radiation temperature higher than the electron cyclotron emission by a few orders of magnitude. An electron density threshold exists to terminate the bursts, and it is strongly dependent on the toroidal magnetic field. The radiation frequency f  is at the plasma frequency, and the frequency bandwidth is very narrow (∼1.5 MHz FWHM, ). The fine structure of the spectrum in the frequency domain has been observed, and the frequency spacing is around 3 MHz. The cavity modes model is capable of explaining the radiation frequency and the frequency spacing. However, a quantitative and complete description of this phenomenon is still lacking.

EASTにおいて、高強度の間欠的放射が定常的に観測されている。放射バーストの持続時間は、数マイクロ秒の特性時間を持つ。この放射は非常に強く、等価放射温度は電子サイクロトロン放射よりも数桁高い。バーストを終了させる電子密度閾値が存在し、これはトロイダル磁場に強く依存する。放射周波数fはプラズマ周波数に等しく、周波数帯域幅は非常に狭い(約1.5 MHz、FWHM)。周波数領域におけるスペクトルの微細構造が観測されており、周波数間隔は約3 MHzである。空洞モードモデルは、放射周波数と周波数間隔を説明することができる。しかしながら、この現象の定量的かつ完全な記述は依然として不足している。
