A low-voltage low-pressure glow discharge with a hollow cathode is discussed. The discharge is ignited in a reflective discharge system with two symmetric peripheral discharge chambers and a common extended hollow cathode at a forevacuum pressure. The plasma parameters and the admissible plasma column diameter in the hollow cathode are determined. It is shown that there is no electric double layer in the region of the output aperture of the cathode cavity.
