Description
Summary:A prototype of a 2 Tesla superconducting transmission line magnet for future hadron colliders was designed, built and tested at Fermilab. This combined function magnet with a 4%/cm gradient and a 1.96 Tesla dipole field has a room temperature iron yoke with two horizontally separated air gaps for beam pipes. The magnetic field in both gaps is generated by a single-turn superconducting transmission line of 90 kA nominal current placed in the center of the iron yoke. The magnetic measurements were made simultaneously in both air gaps using a Hall Probe Station with 102 Hall sensors. The main parameters of Hall Station are briefly described. The magnetic design, pole tip and field quality optimization are presented. The iron saturation effects and their reduction with pole holes are also discussed. The results of magnetic measurements are compared with calculations, design parameters and the quality of magnetic field is discussed
