A high-powered helium microwave-induced plasma was developed, and preliminary characterizations are presented. This kilowatt-plus microwave-induced plasma (KiP-MIP) was contained in a helical flow quartz torch. Power was transferred via waveguides from a 3.0-kW, 2.45-GHz, 120-pulses-per-second microwave generator to a waveguide-to-coaxial converter. A modified Beenakker TM010 resonator cavity was used to focus the energy. Effects of the magnitude of applied power on helium line emission intensities were studied, as well as comparisons of the temporal output of generator output and helium line emission. Introduction of gaseous halogens (Cl2, CBr4) produced intense ion emission which follows the intensity ratios commonly observed in He-MIPs.

Abstract We interpret the recent observations of Otsuji’s team (Sendai) on switching from absorption to amplification at a temperature of T = 300 K during the passage of terahertz radiation through hexagonal boron nitride–graphene sandwiches with multiple gates on the surface with an increase in the electric field in graphene. It is shown that these effects are related to dispersion and negative conductivity near the transit-time frequency of electrons in momentum space under streaming (anisotropic distribution) in graphene in a strong electric field. On the basis of these data, a universal tunable terahertz source is proposed, which has the form of a graphene-containing sandwich with a high-resistance silicon wafer (a cavity) with an applied voltage. This terahertz cavity is a complete analog of the microwave generator implemented on an InP chip by Vorobev’s team (St. Petersburg).
