Autor: Harold Barnard, G.M. Olynyk, Zachary Hartwig, J. Payne

Publikováno v: Fusion Engineering and Design. 87:248-262

The Vulcan conceptual design (R = 1.2 m, a = 0.3 m, B0 = 7 T), a compact, steady-state tokamak for plasma–material interaction (PMI) science, must incorporate a vacuum vessel capable of operating at 1000 K in order to replicate the temperature-depe

Publikováno v: Fusion Engineering and Design. 87:215-223

The steady-state current drive system for the Vulcan tokamak concept has been designed, taking into account requirements of high field, small size, and high operational wall temperature (B0 = 7 T, R0 = 1.2 m, Twall > 800 K). This lower hybrid current
