Since 16th of December until 10th of January 2021, all operating facilities of Forschungszentrum Jülich have been closed and the current stricter corona protection requirements are also being consistently implemented at Heinrich Heine University Düsseldorf. Therefore, as in the spring, only a standby staff will be allowed to work at the Institute and ensure the continued operation of the critical equipment. Many thanks for your commitment and thanks also to all those who are now working in their home offices again instead of doing research! Nevertheless, we hope you have a peaceful holiday season and a good start to a less chaotic new year.
