Abstract :
Trial coil winding of full size coils for the Q1 magnet of the Super High Momentum Spectrometer (SHMS) for JLAB Hall C has been performed under contract by Scientific Magnets Inc. This effort was required to demonstrate that the unique Q1 cold iron quadrupole shape can be executed with a Rutherford type SC cable. Details of the prototype winding tooling, conductor insulation scheme, coil former, the winding process including clamping and curing will be presented. Lessons learned from the initial set of windings were incorporated into the final trail windings of two complete full scale coils that can potentially be used in the actual magnet fabrication. The initial trial windings indicted that the coil end turns would benefit from additional support in the winding form and inclusion of a 5 degree shim along the first turn of the coil would be helpful in improving the fit up of the coils on the symmetry planes, leading to an improved end shape. These changes in coil shape were modeled in TOSCA and the resultant magnetic properties confirmed. The Q1 coils wound were tested for electrical properties, insulation effectiveness and dimensional consistency. Results from the three coils wound will be presented.
