European researchers investigate details of 2021–22 energy crisis
A statistical analysis of the factors behind the 2021–22 energy crisis in Europe is the subject of the article “Patterns and correlations in European electricity prices,” published in the journal Chaos: An Interdisciplinary Journal of Nonlinear Science. The study—conducted by researchers at the Institute for Energy and Climate Research at Forschungszentrum Jülich and the University of Cologne, both in Germany, and the Norwegian University of Life Sciences—describes reasons for the surge in energy prices that go beyond the commonly cited cause of Russia’s invasion of Ukraine.

The largest modular stellarator Wendelstein 7-X (W7-X) has successfully passed commissioning and first phase of operation in Greifswald, Germany. The limiter configurations of plasma with 2.5 T of magnetic induction on the plasma axis produce already considerable loads (MN) in the W7-X systems. The sophisticated W7-X superconducting magnet system with its non-linear support system is instrumented with an extensive set of mechanical and temperature sensors. Measurement results showed that magnet system behavior is in good correspondence with original predictions from numerical models. However, several areas require modeling improvements and/or proper adjustment of parameters to reflect “as-built” situation. Moreover, high temperature dependence of strain gauge signal accuracy in the range below 10 K requires its compensation in order to avoid fault alarms during monitoring. The work is considered as benchmarking of numerical models and as a preparation for upcoming more demanding phases with longer plasma pulses to guarantee safe and reliable W7-X operation with different divertor configurations. Both results of W7-X measurements and implemented improvements as well as lessons learned so far are also given.
