The analysis and measurement of composite coil properties of Jefferson Lab's super high momentum spectrometer (SHMS) superconducting magnet coils
Jefferson Lab's 11 GeV/c Super High Momentum Spectrometer's superconducting cosine(2theta) quadrupole magnets and the cosine(theta) dipole use a Nb-Ti, 36-strand Rutherford style cable wave-solder to a copper extruded substrate as their conductor. These magnets will operate at 4.4 K. Accurate analysis of the mechanical performance of the magnets under Lorentz forces and thermal stresses requires that the composite coil's physical properties at cryogenic temperatures be known. The composite coil design details including the geometry, components, epoxy glass, and its electrical insulation will be presented. The derivation of the composite coil's calculated physical properties values, using a mixing rule and by Finite Element Analysis (FEA) modeling of a sample coil will be given. The calculated values will be compared to recent measured values of representative samples of the composite coils. Comparison of the composite built up coil sample, measurements and calculated values will be discussed
