Summary
It is found that a wave near the lower-hybrid frequency may parametrically excite purely growing instabilities. Modulations by ion cyclotron and collisional modes are considered. The instability thresholds and the widths of the excited spectra are presented.
Riassunto
Si trova che un’onda vicino alla frequenza dell’ibrido inferiore può eccitare parametricamente instabilità puramente crescenti. Si considerano modulazioni dovute a modi ione ciclotrone e collisionali. Si presentano le soglie di instabilità e le ampiezze degli spettri eccitati.
Резюме
Обнаружено, что волна вблизи частоты накачки может параме трически возбудить чисто возрастающие неустойчивости. Рассматриваются модуляции посредством ион-циклотронной моды и столкновительной моды. Приводятся пороги неустойчивости и ширины спектров возбуждения.
