High Field Magnet – Overview

Neutron scattering experiments in combination with strong magnetic fields and low temperatures: This is what the Helmholtz Centre Berlin stands for. Bombarding samples with neutrons in an extremely strong magnetic field: there is no place in the world where you will find more know-how to do this and thus to research the most topical issues in physics, chemistry, biology, and material science.

Model of the High Field Magnet in neutron guide hall II

At the Helmholtz Centre Berlin for materials and energy – formerly Hahn-Meitner-Institut- a new high field magnet is under construction: internationally unique and with a magnetic field strength of 25 to 30 Tesla, which is about one million times stronger than the earth’s magnetic field and thus the strongest magnet for neutron scattering experiments in the world.

The project was approved by the Federal Ministry of Education and Research in February 2007 with a total investment costs about 20 million € and a construction time of around five years.

The ExED (Extreme Environment Diffractometer), the relevant instrument for neutron detection, is located in the neutron guide hall II which was completed in 2005.
