Abstract :
Fireballs is a generic name for the many forms of anode glow phenomena in low-pressure gas discharges. The glow indicates energetic electrons impacting with neutrals. A sharp boundary of the glow suggests a localized electric field such as a sheath or double layer. Fireballs mostly appear as spheres and cylinders, but new forms have been observed in dipole magnetic fields. The dynamics of pulsed and unstable fireballs has been investigated.
