给出了逃逸电子在氮气中引发的脉冲周期放电等离子体辐射的幅值-时间和光谱特性的实验研究结果。放电是由重复频率为60 Hz的高压纳秒电压脉冲在锥形电位阴极和平面接地铝阳极之间的间隙中的急剧不均匀的电场中引发的。在给定的激发条件下，在放电等离子体的发射光谱中观察到Al I原子和Al II原子离子的强谱线、N I原子和N II离子的强谱线、第一（1 +）和第二正（2 +）氮体系的谱带以及氰CN的谱带。
Results of experimental investigations of amplitude-temporal and spectral characteristics of radiation of a pulse-periodic discharge plasma initiated in nitrogen by runaway electrons are presented. The discharge was initiated by high-voltage nanosecond voltage pulses with repetition frequency of 60 Hz in a sharply inhomogeneous electric field in a gap between the conic potential cathode and the planar grounded aluminum anode. It is established that intensive lines of Al I atoms and Al II atomic ions, lines of N I atoms and N II ions, bands of the first (1 + ) and second positive (2 + ) nitrogen systems, as well as bands of cyanogen CN are observed in the emission spectrum of the discharge plasma under the given excitation conditions.
