How it works

Unfortunately, it is not possible to wake up in the morning with the idea to do an experiment with neutrons or x-rays out of the blue. One has to prepare this well in advance!

For x-ray experiments at GALAXI, just get all the information here.

Dedicated neutron scattering instruments are provided by JCNS at:

Beam time at the MLZ instruments is offered to scientists from all over the world regardless of the country in which they are conducting their research, while beam time at the ILL and SNS instruments is provided to German affiliated users only.

In order to transform your idea into a publication via a successful experiment, please follow the steps below. The links will offer detailed information. Be aware: There are several small differences within the workflows at MLZ and at the ILL – so please make sure you studied the page for “your” location well!



  • submit a proposal at MLZ or ILL
  • meet the deadline
  • proposals will be reviewed by the MLZ Review Panels based on scientific merit


  • meet the location’s requirements for your visit at MLZ or ILL
