A Proof of Principle Experiment (POPE) has been constructed and conducted to demonstrate the stability and operation of the SMES conductor in the SMES-WISC team's Engineering Test Model (ETM) design. The experimental facility includes: a 100 kA DC power supply; a 4 tesla, 1 meter bore, background field split solenoid; a three turn-1 meter diameter test coil of the ETM conductoG a dewar for operation of the solenoid and test coil at 1.8 K and 1 atmosphere, and support syskms for vacuum, helium

We report on measurements of conductor stability vs. transport current, applied magnetic field, and cooling from liquid helium. The measurements characterize the conductor's stability against finite length traveling normal zones, and against quenches resulting from transient normal zones. The data qualify the conductor for dependable use at 50 kA, 4 tesla and 1.8 K.
