On Friday, October 30, 2026, Timoth\u00e9 Auclair successfully defended his dissertation on the contribution of high-critical-temperature superconductors to the design of power-generating tokamaks. He thus becomes the first PhD graduate from the PEPR SupraFusion program and the SF-Plant project, marking an important milestone for the program and its teams.<\/strong><\/p>\n

Superconductors for More Compact Fusion Power Plants<\/h3>\n

High-temperature superconductors (HTS) hold significant potential for the design of future fusion power plants. Capable of withstanding magnetic fields far stronger than those achievable with conventional superconductors, they could enable the design of more compact and potentially less expensive tokamaks.<\/p>\n

However, the increase in the magnetic field also places considerable mechanical stress on the machine’s structures. Timoth\u00e9 Auclair’s research sought to address this issue.<\/p>\n

D0FUS: an open-source tool for sizing tokamaks<\/h3>\n

As part of his thesis, Timoth\u00e9 developed D0FUS<\/strong> , an open source code written in Python, dedicated to the sizing of tokamaks.<\/p>\n

This tool combines a plasma physics calculation chain\u2014which, among other things, determines stability limits\u2014with original electromechanical models for coil design. Validated module by module, D0FUS accurately reproduces the characteristics of several machines.<\/p>\n

It has thus made it possible to identify the key factors for ensuring the viability of fusion reactors operating under high magnetic fields.<\/p>\n

SF-Plant: Promising results for future fusion power plants<\/h3>\n

The results of this research find concrete application in SF-Plant<\/strong> , the fusion power plant project developed within the framework of the PEPR SupraFusion.<\/p>\n

The proposed design meets the objectives set for EU-DEMO, with a fusion power of 2 GW and an energy amplification factor (Q) greater than 40, while exhibiting particularly promising characteristics:<\/p>\n
