太赫兹(THz)频段电磁辐射准光束中气体放电的研究具有重要的基础和应用价值。太赫兹频段独特而可靠的辐射源的出现，使得对这种放电的研究成为可能。应用物理研究所(下诺夫哥罗德)研制出了太赫兹波段(回旋管)电真空辐射源，脉冲工作功率量级为100kW(脉冲宽度~几十微米S)，连续工作功率量级为千瓦，并开始了对各种气体中气体放电现象的研究。即使是对惰性气体(Ar)放电的第一次实验研究也表明，太赫兹放电与低频放电有很大的不同，甚至在放电辉光的动力学方面也是如此。在太赫兹脉冲结束后观察到放电辉光的最大值，余辉持续时间为数百微秒。本文对各种气体在263 GHz和670 GHz辐射下的击穿阈值进行了理论和实验研究，并对670 GHz辐射作用下稀有气体和分子气体的放电动力学进行了研究。
The study of the gas discharge in quasioptical beams of electromagnetic radiation of the terahertz (THz) frequency band is attractive for fundamental and applied research. The study of this discharge was made possible by the emergence of unique and reliable sources of radiation of the THz frequency band. Electrovacuum radiation sources of THz band (gyrotrons) have been created at the Institute of Applied Physics (IAP RAS) (Nizhny Novgorod) with a power order of 100 kW in pulsed mode of operation (pulse duration ~ several dozens of µs) and a kilowatt in continuous mode, and investigations of gas discharge phenomena in various gases have been started. Even the first experimental studies of the discharge in noble gases (argon) showed a significant difference in the THz discharge from the discharge at lower frequencies, even in the dynamics of discharge glow. The maximum of the discharge glow was observed after the end of the THz pulse and the afterglow duration was hundreds of microseconds. This paper is devoted to the theoretical and experimental study of the breakdown thresholds of various gases by radiation at 263 and 670 GHz and the study of discharge dynamics in noble and molecular gases under the action of 670 GHz radiation.
