Abstract
The contribute describes and analyses some recent experimental results obtained at the High Voltage Padova Test Facility (HVPTF) The results of four voltage hold -off experiments adopting stainless steel electrodes are presented and discussed. The conditioning histories in high vacuum, obtained by a fully automatic procedure, have been compared and analysed. A marked total voltage effect has been observed for gap lengths longer than 70 mm. The best hold -off performances in medium vacuum, up to 800kV, the limit of the system, were obtained by the stationary injection of Ar.File in questo prodotto:
