Abstract :
A joint in the superconductor and stabilizer is added to the ETM conductor in the POPE. The joint design is similar to that proposed by Westinghouse for the SMES ETM field joints. Fabrication of the joint is described. Measurements on the performance of the superconducting joint operated in subcooled He II and of the stabilizer joint at 14 K are reported. Measured superconductor joint resistance is 1.6 n/spl Omega/, which agrees with previous analytic calculations. The stabilizer joint RR matches the conductor stabilizer RR. The joint met or exceeded all operational requirements throughout the experiment demonstrating its reliability and small joule heating.<>
