SPARC
SPARC is Commonwealth Fusion Systems (CFS) and MIT Plasma Science & Fusion Center's (PSFC) proposed Tokamak using high-field magnets built with a newly available high temperature superconductor (HTS). This experiment would be the first controlled fusion plasma to produce net energy.
Ken studied sites, buildings, subsystems configurations, Tokamak assembly, and eventually led the facilities design and the team of architects and engineers executing the work in Devens, MA.

MIT Plasma Science & Fusion Center Hinged HTS Tokamak Design Study
This conceptual Tokamak study incorporates: REBCO High Temperature Superconducting TF and PF Electromagnets; Replaceable 3D Printed Vacuum Vessel; Hinged TF Coils; FLiBe Molten Salt Blanket (Neutron Shielding, Heat Transfer, Tritium Breading, and Vacuum Vessel Cooling); High-Field-Side Lower Hybrid RF Plasma Launcher.
Ken explored subsystems geometries, Tokamak Assembly and vessel replacement.
