Abstract

Operational windows in major radius (R) and toroidal field (B) space for fixed ignition margin are calculated for the Ignifed and Inconel candidate CITs. The minimum R bounds are predominantly physics limited, and the maximum R portions of the windows are engineering limited. For a modified Kaye-Goldston plasma energy confinement scaling, the minimum size is 1. 15 m for the Ignifed device and 1. 25 m for the Inconel device. With the Ignition Technical Oversight Committee physics guidance of B**2a/q* and I//p less than 10 MA, the Ignifed and baseline Inconel devices have minimum sizes of 1. 2 and 1. 25 m and torodial fields of 11 and 10. 4 T, respectively. Sensitivity studies show Ignifed to be more sensitive to coil temperature changes than the Inconel device, whereas the Inconel device is more sensitive to stress perturbations.
