Steady state, core, operational optimization of an ARC-like tokamak via plasma composition and shape

A. Saltzman, P. Rodriguez-Fernandez, A. Ho, G. Snoep et autres

Impurity composition, plasma shape, and pedestal density all provide strong levers on fusion power. Here, we explore the ways in which their variation changes fusion power and seek to find the optimum of these parameters. The key impacts of these variables are …

The separatrix operational space of next-step fusion experiments: From ASDEX Upgrade data to SPARC scenarios

T. Eich, T. Body, M. Faitsch, O. Grover et autres

Fusion power plants require ELM-free, detached operation to prevent divertor damage and erosion. The separatrix operational space (SepOS) is proposed as a tool for identifying access to the type-I ELM-free quasi-continuous exhaust regime. In this work, we recast the SepOS framework using …

Overview of the early campaign diagnostics for the SPARC tokamak (invited)

M.L. Reinke, I. Abramovic, A. ALBERT, Keisuke Asai et autres

The SPARC tokamak is a high-field, Bt0 ∼12 T, medium-sized, R0 = 1.85 m, tokamak that is presently under construction in Devens, MA, led by Commonwealth Fusion Systems. It will be used to de-risk the high-field tokamak path to a fusion power …

JET machine operations in T&D-T

E. Abdelrahman, Azizah Abdul Hamid, N. Abid, K. Abraham et autres

Abstract JET, the world’s largest operating tokamak with unique Be/W wall and tritium handling capability, completed a Deuterium-Tritium (D-T) campaign in 2021 (Maggi et al 29th Fusion Energy Conf.) following a decade of preparatory experiments, dedicated enhancements, technical rehearsals and training (Horton …

Overview of Results from the National Spherical Torus Experiment (NSTX)

Princeton Plasma Physics Lab. (PPPL), Princeton, NJ (United States), D. Gates, USDOE Office of Science (SC), J. Ahn et autres

The mission of NSTX is the demonstration of the physics basis required to extrapolate to the next steps for the spherical torus (ST), such as a plasma facing component test facility (NHTX) or an ST based component test facility (ST-CTF), and to …
