Abstract:The electric breakdown along the insulator in a plasma focus (PF) device is fundamental for the formation of a homogeneous and symmetric current sheath. From this point of view, the primary electron emission is essential to set the appropriate initial conditions. In this paper, the authors study the effect and viability of an unpolarized ferroelectric lead germanate Pb 5 Ge 3 O 11 thick film covering the alumina insulator of a 400-J Mather-type PF device on the plasma formation and evolution during the dischar… Show more
