This paper reports on test results from the 200 kA SMES/ETM conductor. The critical current and stability margin of a 200 kA, copper-stabilized, cable-in-conduit conductor cooled with helium-II has been measured at the Texas Accelerator Center. The test specimen was 3 meters long, inserted in a uniform background dipole field of up to 5 Tesla with an effective length of 0.9 meters. The critical current of the conductor was measured at 1.8 K and found to be 280 kA at a total field of 5.8 T, 260 kA at 6.4 T, and 215 kA at 7.4 T, in good agreement with extrapolations based on 4.2 K short sample data. Normal zones of 2 cm initial length were initiated by inductive heaters, and the voltage and temperature of the conductor in the heated zone was monitored for recovery of propagation.
