Powerful, self-stabilized, longitudinal, multiatmospheric-pressure discharge
Bokhan P. A. , Zakrevskii D. E.
A powerful periodic-pulse longitudinal discharge at multiatmospheric pressure in mixtures of helium with metal vapors was produced and investigated. It was shown that as an impurity-controlling ionization, the metal vapor ensures that a uniform discharge will function in large-diameter tubes (~3 cm) at least up to mixture pressures of 5 atm and per-unit-length excitation power —25 kW/m. The discharge obtained is used to pump powerful metal-vapor ion lasers. © 1995 American Institute of Physics.
