A triple-wave resonance model for the emission from tokamaks of narrow-band radiation at the plasma frequency

When the distribution of electron velocities parallel to the magnetic field has a tail with a bump, a linear triple-wave resonance instability can cause the growth of electromagnetic waves at ωp. The bandwidth of the radiation depends on the ratio of the number of electrons in the tail to the total number of electrons; the smaller this ratio, the narrower the bandwidth. The instability occurs only when the mean tail velocity has a specific value. The radiation thus gives an indication of the tail structure.

磁場に平行な電子速度分布がテール(尾部)にバンプ(突起)を持つ場合、線形三重波不安定性により、ωpにおける電磁波の成長が引き起こされ得る。この放射の帯域幅は、テール内の電子数と全電子数との比に依存し、この比が小さいほど帯域幅は狭くなる。この不安定性は、平均テール速度が特定の値を持つ場合にのみ発生する。したがって、この放射はテール構造の指標を与える。
