Study on Ferroelectric Thick Film Insulator Sleeve On Plasma Focus
- Comision Chilena de Energia Nuclear, Casilla 188-D, Santiago (Chile)
The effect of ferroelectric lead germanate Pb5Ge3O11 (PGO) thick film in the alumina insulator sleeve of the 400 Joule Mather-type plasma focus device, PF-400J is studied. The breakdown phase along the insulator is fundamental for the formation of a homogeneous and symmetric current sheath, that is essential for a good plasma pinching, high neutron yield and X-ray emissions. For over several hundreds of electrical discharges, the films show good mechanical and electric performance. From the beginning the operating system is highly reproducible, shot to shot, with a clear definition of the plasma pinch on the axis of discharge. The grade of influence of the electron emission from the ferroelectric is experimentally studied.
