Current-carrying leads can constitute a major source of heat leak into cryogenic apparatus. The geometry of the optimum lead for a given application is not obvious. Minimizing conducted heat requires the longest possible length and the smallest possible cross-section; minimizing generated I 2 R heat requires the exact opposite.
