    Abstract

    The use of methane in a non-self-consistent discharge controlled by an electron beam permits obtaining high discharge currents for relatively low electric fields. The current gain is 103for 500 V/cm fields and a 14 mA/cm2 injection current density. For fields greater than 7-8 kV/cm and atmospheric pressure, punch-through of the gas discharge gap occurs. It is shown that a breakpoint in the CVC in the area of low currents is associated with the appearance of spots on the cathode. A domain Instability, related to the nonmonotonic dependence of the drift velocity on the reduced field in methane, is detected.
