Low-Pressure Dynamical Glow Discharge With Electrolytic Cathode in the Form of Aqueous Solution of $\hbox{NaHCO}_{3}$

Video images of a low-pressure dc glow discharge with an electrolytic cathode in the form of aqueous solution of sodium bicarbonate NaHCO
₃
are presented in this paper. Various forms of the discharge are observed. One of the discharge forms-a dc glow discharge with a foam cathode-was recorded for the first time. A space-time diagram of the discharge is drawn.
