Abstract

A 35 T Hybrid magnet is to be installed at the National High Magnetic Field Laboratory at Tallahassee. The superconducting background field magnet of this system consists of three coils, two of niobium-tin conductor and one of niobium-titanium. This paper describes the design and construction of the niobium-titanium section. In the design, three issues of principal importance were considered: stability and dissipation under pulsed and steady state conditions; the stressing of the conduit, and the consequences of quenching. The details of construction have centered around the winding and assembly of the pancake coils and the preparation of the joints. The construction of the coil is part of a collaborative program between MIT and FSU
