[SUPERSEDED] The Admissible Operating Window - Which Constraints Actually Bind
Year: 2026
Type: preprint
Abstract: This record has been superseded. The current, updated version is Lifetime-Constrained Operating-Window Synthesis for a Compact Spherical-Tokamak Breeder: The Source-Strength-Centrepost-Life Trade and the Admissible Current Window (DOI 10.5281/zenodo.22645799). Please read and cite the current version. This page stays online so existing citations keep resolving. The operating window synthesized from two findings: a strict invariance — source strength and wall loading trade one-for-one against centrepost life across the whole density–temperature plane, so there is no free operating-point gain — and a coupled admissible-current window whose floor is the q95/MHD edge and ceiling the centrepost fluence, with the tritium-startup requirement non-binding at ~1.7× margin.
