High Field Magnet – Overview
Neutron scattering experiments in combination with strong magnetic fields and low temperatures: This is what Helmholtz-Zentrum 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.
The Helmholtz-Zentrum Berlin has installed an internationally unique High Field Magnet with a magnetic field strength of 26 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.
After closure of the neutron source BER II, the high field facility is no longer available for neutron scattering experiments.
The project was approved by the Federal Ministry of Education and Research in February 2007 with a total investment costs about 20,8 million € and a construction time of around eight 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.
The high field magnet was developed in Collaboration with the National High Magnetic Field Laboratory, Florida. According to reasons of formal law, the co-operation partner of Helmholtz-Zentrum Berlin is a not-for-profit corporation, the "Florida State University Magnet Research and Development, Inc.".
