[en] The results of a conceptual design study of an ignition test reactor with niobium--titanium superconducting toroidal field coils are presented. This reactor, which is designed to reach ignition conditions and provide a plasma burn of 30 seconds, has a major radius of 3.8 m, a plasma minor radius of 1.1 m, and a doublet plasma height-to-width ratio of 2.7 m. These specifications were derived from parametric sstudies in which the overall cost was minimized for a reactor providing a modest ignition margin with Alcator scaling. The remote maintenance system is briefly described. While the reactor is designed so that contact maintenance can be performed on components outside the shield envelope, special equipment is designed to gain access to components inside the shield envelope and to permit direct observation and limited adjustments during setup procedures
