Abstract

The Muon-to-Electron conversion experiment, under development at Fermilab, utilizes a complex superconducting solenoid magnet system. Usage of high temperature superconductor (HTS) power leads and reliable superconducting bus system and splice joints are essential to the assuring safe, continuous and cost effective operation of the magnets. Left over HTS power leads from the Tevatron era combined with superconducting bus (made from aluminum-clad NbTi Rutherford cable) and three different types of splices were successfully tested in a single dewar test configuration up to 10150 A. In this paper we summarize the test results.
