Niobium--tin deals toroidal magnet system for a high field ignition test reactor

Using a High Field Ignition Test Reactor application based on the Tokamak magnetic confinement approach, a three-month study effort focused on developing a feasible demountable DEALS toroidal magnet system design which would simplify the construction of the magnet and reactor, as well as facilitate future maintenance during long-term operation. This target was successfully achieved. The overall DEALS design is described, together with the basic reactor parameters. Detailed stress analyses for the support structure are given, together with magnet and conductor specifications. Preliminary electrical contact tests relating to joint design are also discussed.
