Test of a NbTi Superconducting Quadrupole Magnet Based on Alternating Helical Windings

It has been shown that by superposing two solenoid-like thin windings, that are oppositely skewed (tilted) with respect to the bore axis, the combined current density on the surface is cos(thetas) -like and the resulting magnetic field in the bore is a pure dipole field. Following a previous test of...
