The High-Field Test Facility (HFTF) being built at Lawrence Livermore National Laboratory (LLNL) consists of a Set of four Nb-Ti coils, inside of which there is a oair of niultifilamentary NbjSn coils. The outer coils are designed lo generate 8 T in the l-m bore; the M>3Sn coils will boost this to 12 T in a 40-crn bore.This paper describes the first operation of the complete set of Nb-Ti coils and describ.es and gives results from the data acquisition and analysis sys tem that was used during the test.
A solenoid coil, 105 cm inside and 167 cm out side diameter, has been constructed and tested to study the performance of the stabilized Nb-Ti conductor to be used in the Mirror Fusion Test Facility (MFTF) being built at Lawrence Livermore Laboratory. The insulation system of the test coil is identical to that envisioned for MFTF. Cold-weld joints were made in the conductor at the start and finish of each layer; heaters were fitted to some of these joints and also to the conductor at various locations in the winding. This paper gives details of the construction of the coil and the results of the tests carried out to determine its propagation and recovery characteristics,
