Novel internal measurements and analysis of ion cyclotron frequency range fast-ion driven modes in DIII-D are presented. Observations, including internal density fluctuation () measurements obtained via Doppler backscattering, are presented for modes at low harmonics of the ion cyclotron frequency localized in the edge. The measurements indicate that these waves, identified as coherent ion cyclotron emission (ICE), have high wave number, k⊥ρfast ≳ 1, consistent with the cyclotron harmonic wave branch of the magnetoacoustic cyclotron instability, or electrostatic instability mechanisms. Measurements show extended spatial structure (at least ∼1/6 the minor radius). These edge ICE modes undergo amplitude modulation correlated with edge localized modes (ELM) that is qualitatively consistent with expectations for ELM-induced fast-ion transport.

DIII-Dにおけるイオンサイクロトロン周波数帯域の高速イオン駆動モードの内部測定と解析を提示する。ドップラー後方散乱により得られた内部密度揺動(\(\tilde{n}_e/n_e\))測定を含む観測結果を、周辺部に局在するイオンサイクロトロン周波数の低次高調波におけるモードについて示す。測定結果は、これらの波がコヒーレントなイオンサイクロトロン放射(ICE)として同定され、高い波数を有すること(k⊥ρfast ≳ 1)を示しており、これは磁気音響サイクロトロン不安定性のサイクロトロン高調波分枝、または静電的不安定性機構と整合する。測定により、少なくとも約1/6の小半径に及ぶ拡がった空間構造が示される。これらの周辺ICEモードは、周辺局在モード(ELM)に相関した振幅変調を示し、これはELM誘起の高速イオン輸送に対する期待と定性的に整合する。
