Nature and technology are full of dynamics, often involving multiple scales in length, time and energy. To model these processes, we combine scientific computing with model reduction and machine learning, with particular focus on plasma dynamics in lightning and space weather, and in high voltage and plasma technology.

Our research addresses questions in nature such as start and propagation of lightning strokes, terrestrial gamma-ray flashes and space weather, and closely related technological problems such as switch gear for long-distance electricity nets, air purification and disinfection with corona reactors, and protection of satellites and electricity nets from space weather.

Within national and European projects, we collaborate with colleagues in applied plasma physics, electrical and mechanical engineering, atmospheric electricity, and cosmic particle and space science, and with non-academic partners such as ABB, DNV-GL, ESA-ESTEC and NASA.

In Memoriam Willem Hundsdorfer

In Memoriam Willem Hundsdorfer

With sadness, we let you know that our colleague Prof. Willem Hundsdorfer passed away on Friday 10 November, at the age of 63. Since 1984 Willem had been affiliated with CWI; first in the Numerical Mathematics department, where he built up an international reputation. Since 2002, he had been part of the Multiscale Dynamics research group, where he shared his expertise for developing simulations of electric discharges that by now are widely recognized.

Vidi grant for Enrico Camporeale’s space weather research

Vidi grant for Enrico Camporeale’s space weather research

CWI researcher Enrico Camporeale received a Vidi grant from NWO for his proposal 'Real-time forecasting of killer electrons on satellite orbits' in May 2017. He received the 800,000 euro grant to develop his own innovative line of research and to set up his own research group within five years. Camporeale will develop a technology to forecast space weather events that could harm satellites, power networks and communication systems. This forecast would allow to take countermeasures.
