摘要：
It is demonstrated experimentally that the lifetime of the afterglow plasma of a high-current pulsed discharge in a dielectric tube filled with a mixture of argon with saturated mercury vapor is longer than 1 ms. Such a long lifetime, during which the electron density decreases from 10(14) to 10(12) cm(-3), is explained by the chemi-ionization of mercury vapor by long-lived metastable argon atoms. During this time, the after-glow plasma can serve as a microwave waveguide for a weakly damped low-noise E-0-type axisymmetric surface mode, which allows one to use it for transmission of signals in the centimeter wavelength range.
