Abstract

This paper deals with breakdown voltage characteristics of saturated liquid helium, in the presence of a metallic particle in shape of needle or sphere to obtain insulation design data for the pool-cooled low temperature superconducting coil and to find the factors dominating the breakdown voltage. The results show that the lowest breakdown voltage appears at a free needle particle which produces bubble-generation, rich initial electrons and high stress electric field.
