The onset and development of an instability on a liquid-helium surface charged by electrons localized over the surface are investigated. It is established that the electrons leave the surface by formation of bubblons (bubbles filled with electrons) containing 107—108 electrons and having dimensions 0.05-0.03 mm. Small-diameter bubblons are stable in a field of 1 cgs esu and move in the helium with a steady-state velocity ~104 cm/sec.
