Abstract :
The breakdown strength of liquid helium (LHe)-filled gaps depends strongly on gap size, which is typical for a weak-link dominated breakdown. However, the theoretical basis as derived from Weibull distributions does not fit into the size effect. The real probability distributions in LHe seem to be more complex. The particular implications are discussed in the paper. It comes out that the true size effects can only be measured directly
