用转镜式扫描光谱仪获得了微型环流器放电中不同时刻的氢等离子体的扫描光谱及氢原子光谱的H_α和H_β谱线的瞬时轮廓。根据谱线的多普勒展宽,测定了放电期间离子温度随时间的变化;亦观察了在发生破裂不稳定性时离子温度的变化。
The scanning spectra of the hydrogen plasma and the instantaneous profiles of the H_α and H_β spectra of the hydrogen atom spectra at different times in the microcirculator discharge were obtained by using a rotating mirror scanning spectrometer. According to the Doppler broadening of the line, the change of ion temperature with time was measured during discharge. The change of ion temperature in the event of rupture instability was also observed.
