项目摘要
The PI will measure HF induced ionospheric Langmuir turbulence at high resolution Arecibo and EISCAT enhanced plasma line spectra, hoping to locate the cascade spectrum relative to matching and reflection heights during daytime experiments. He will perform low HF duty cycle experiments with increased HF power to investigate the effects of increased power on the free mode physics, as well as experiments observing the effect of magnetic field geometry on observations of the normal HF-induced plasma line, and on HF enhanced outshifted plasma line. Moreover, he will perform nighttime observations during low HF duty cycle heating using the 'chirp' technique to better compare daytime results with nighttime coded long pulse experiments. Finally, time permitting, he will vary the HF duty cycle to measure HF irregularity-induced broadening of the natural plasma line at Arecibo and EISCAT.
PI将在高分辨率Arecibo和EISCAT增强等离子体谱上测量HF诱导的电离层朗缪尔湍流,希望在白天实验期间定位级联谱相对于匹配和反射高度。 他将进行低高频占空比实验,增加高频功率,以研究增加功率对自由模物理的影响,以及观察磁场几何形状对正常高频诱导等离子体线观察的影响的实验,以及对高频增强的外移等离子体线的实验。 此外,他将在低高频占空比加热期间使用“啁啾”技术进行夜间观测,以更好地将白天的结果与夜间编码长脉冲实验进行比较。 最后,如果时间允许,他将改变高频占空比,以测量在阿雷西博和EISCAT的自然等离子体线的高频不规则性引起的增宽。
