Abstract :
A superconducting transmission line magnet test facility was built and commissioned at Fermilab. The test facility is capable of generating a 100 kA current in a 17-meter length short-circuited superconducting loop, as well as driving 15 m long test magnets. The current is excited by a room temperature primary winding and iron yoke operated as a current transformer. This approach avoids the expense and difficulty of 100 kA current leads, and allows the facility to be Dewar-based. The loop has a replaceable superconductor section 4 m long for testing various types of VLHC transmission line cables. The system design, 3D magnetic field analysis, magnetic force distribution and test results are discussed.
