DRESDYN - A new liquid sodium facility for experimental studies of dynamo action and related instabilities

The DREsden Sodium facility for DYNamo and thermohydraulic studies (DRESDYN) will comprise large scale liquid sodium experiments related to geo- and astrophysics as well as experiments for safety and thermohydraulic studies related to sodium fast reactors and liquid metal batteries. The most ambitious parts of DRESDYN are a homogeneous dynamo driven solely by precession, and a large Tayler-Couette type experiment for the combined investigation of the magnetorotational instability and the Tayler instability. After a short summary of our previous achievements we delineate the next steps for the realization of DRESDYN.
