Overview/Agenda

The Simons Collaboration on Hidden Symmetries and Fusion Energy organises a workshop on Stellarator optimisation in Greifswald 27 June - 8 July. The objective of the workshop is to provide an opportunity for the exchange of ideas and collaborative work in a relaxed atmosphere. The workshop is open to members of the Collaboration and to scientists from the wider community who work in the field of stellarator optimisation.

(Registration ended on 15 May 2022).    Link to Simons Greifswals Workshop on Max Planck website
