Abstract

A prototype of the transmission line magnet for the Very Large Hadron Collider is being designed at Fermilab. This is a single-turn warm iron superconducting magnet in a "Double-C" configuration. Iron poles form a high quality alternating-gradient magnet field in two 20 mm height beam gaps. Simple magnet construction and manufacturing processes and a room temperature iron yoke give a significant reduction in magnet cost. Open beam gaps simplify magnetic measurements and vacuum chamber installation. The magnet mechanical stability was investigated for several mechanical models. A high field quality over the whole range (0.1 T-2.0 T) of field variation was calculated using correcting holes in the iron poles. The magnet optimization was carried out by POISSON, OPERA 2D and ANSYS codes. The results of magnet design and model tests are presented.
