Current-voltage Characteristics of the high Pressure Reflex Discharge in Helium

In this paper the high pressure reflex discharge is investigated. Conditions for the discharge transition from a low-current to a high-current mode are considered. The study of the discharge is carried out in the atmosphere of helium at pressures from 1 to 35 mTorr, with a magnetic field up to 2.1 kG and voltage up to 1.2 kV. The radial profile of the potential distribution in the central plane of the discharge (perpendicular to the axis) was obtained by the isolated probe method.
