Description

The recent discovery of superconducting properties in MgB2 and rapid development of small diameter steel-clad wires has opened up the possibility of enhancing the design of the baseline Astro-E2 high current lead assembly. Replacing YBCO filaments with MgB2 wires and modifying the heat sink location can give much higher margins against quench from temperature oscillations of the 4 K heat sink, although with some overall thermal penalty. The design and performance of a new lead assembly during flight qualification is discussed, with emphasis on thermal, structural, and electrical test results
