II/2021

Dear MLZ users,

welcome to our last newsletter in 2021! We all are ready for restart next year and thus you will learn a lot about developments at the instruments during the past months and what we plan for the next future.

Enjoy reading, stay safe and healthy, – and see you next week?!

Editorial

The thermal intermezzo

After quite a long absence of neutrons at the MLZ due to the Corona pandemic, we unfortunately faced a technical issue with the cold source of the FRM II in spring this year. Careful analysis of the situation yielded that the cold source had to be removed and will be replaced after a transition period of “thermal operation”.

This particularly affects all instruments in the Neutron Guide Hall West. Detailed simulations of the neutron flux at the instruments anticipated in the thermal scenario show that a user programme for the “cold instruments” starting in March 2022 will be possible. Updated information on the specific instruments is provided at our MLZ home page, and you are welcome to discuss with our scientists at the MLZ User Meeting next week.

We are very much looking forward to welcoming our users again soon! In order to mitigate possible effects of the pandemic on travel plans we are well prepared for the many facets of remote collaboration before, during and after your experiments, which gives all of us an optimistic perspective for the next year!

Running without cold source

The MLZ will run without cold source for the next time. What does this really mean for the instruments?

At a glance

No neutrons do not mean that there are no news from the instruments! Just visit the gallery and learn about some of them in a short way.

From an instrument's point of view

How did an instrument experience the last months? Let’s ask RESEDA, our resonance spin echo spectrometer! (And why does its instrument scientist Johanna K. Jochum sit on that box???)

Neutrons unravel 50-year-old physics mystery

More than 50 years ago, researchers discovered a pronounced phase transition in strontium iron oxide at room temperature. However, what exactly happens in this process at the atomic level has been unclear ever since.
