THE WISCONSIN PEGASUS SOLENOID

A 1.6 m long x 0.1 m diameter coil has just been constructed by the NH MFL for the University of Wisconsin Pegasus Tokamak. It will form the central solenoid for the high plasma energy density fusion machine. Th e magnet consists of two layers of Glidcop conductor, reinforced with S2 glass, carbon fiber and steel. Normal operating parameters will be 14 T in a 58 mm bore with a number of pulses to 20 T+. Current densiti es will approach 1 kA/mm(2) and the stored energy will be > 2 MJ. The philosophy behind the design will be presented and details of the cons truction and testing will be shown. (C) 1998 Elsevier Science B.V. All rights reserved.
