Summary
After emerging from the cathode sheath of a low voltage arc at low pressure, the primary electrons excite and participate in an u.h.f. oscillation in the plasma. This attains large amplitude rather abruptly a few mm from the cathode. The present paper contains a concise description and brief commentary on discharges of this type and of their relation to some other forms of u.h.f. and lower frequency discharges. Most of the processes involved are probably markedly non-linear. The possibility of electrical turbulence is mentioned.
