EUROfusion E-TASC General Meeting #2

9 Feb 2026, 13:00 → 13 Feb 2026, 13:00 Europe/Berlin

D2 Conference Room (Max Planck IPP)

The General Meeting offers a valuable opportunity to collectively deliberate on key issues shaping both the current operations and the strategic direction of E-TASC. Discussions will focus on several core themes:

• Strengthening collaboration and networking across Work Packages focused on Theory and Modelling development (DSO, WPTM, and EnR-MoD).

• Developing strategies to maximize the impact of ACHs and computing resources.

• Ensuring the timely release and operational readiness of simulation tools throughout 2026–2027.

• Promoting the dissemination of developed research software and training activities.

The meeting will feature a combination of plenary sessions and parallel breakout discussions, providing extensive opportunities for in-depth inter-project engagement.

If you have pressing topics that warrant attention at the global E-TASC level, or would like to propose a specialized discussion group, please contact us at your earliest convenience. Your input is essential to refining the agenda and ensuring it reflects the priorities and interests of all contributors.

Your input is vital in refining our agenda and ensuring it addresses the interests of all contributors.
