The Institute High Magnetic Field Laboratory Dresden ( HLD) (also: High Magnetic Field Laboratory ) at the Helmholtz -Zentrum Dresden -Rossendorf ( FZD ) is concerned with modern materials research in very high magnetic fields. It serves as a research facility for their own projects, as well as a user facility and provides opportunities for experimentation in pulsed magnetic fields up to 90 Tesla in routine operation at. In addition, field values ​​have been obtained up to 94.2 Tesla. The aim is magnetic to the feasibility limit of about 100 Tesla.

Genesis

In 1999, the Dresden High Field initiative requested the establishment of the High Magnetic Field Laboratory at the Federal Ministry of Education and Research (BMBF) and the Saxon Ministry of Science and Art ( BSEC ). On the recommendation of the Science Council core funding was approved and in 2003 the construction of the high-field laboratories began on the site of HZDR. The investment costs amounted to 24.5 million euros and were shared equally by the federal government and the Free State of Saxony. In December 2004, the Institute was established under the direction of Prof. Dr. Joachim Wosnitza.

User operation

Since its completion in 2007, it is possible to use also for external researchers. The measuring time allocation coordinates the HLD together with the European high- field centers in Grenoble, Toulouse (both LNCMI ) and Nijmegen ( HMFL ) in the context of the EU project EMFL.

Research

As the only laboratory in Europe, the High Magnetic Field Laboratory Dresden offers access to a magnet with a magnetic flux density of 94.2 Tesla over a pulse duration of 11 milliseconds in a diameter of 16 millimeters. Similar to strong magnetic fields may otherwise be generated only in the National High Magnetic Field Laboratory in Los Alamos, United States. In addition, the HLD has several Tesla coils 70 with pulse durations of 150 ms.

The HLD develops and produces the solenoid itself because of the high magnetic pressure must be wrapped with an extremely tear-resistant synthetic fiber wire turns of these coils. The aim is to achieve a field strength of about 100 Tesla, a pulse duration of 10 milliseconds. The required energy of 50 MJ is made using the world's biggest developed specifically for this laboratory capacitor bank.

Primarily, the electronic properties of metallic, semiconducting, superconducting and magnetic materials are studied in high magnetic fields at the HLD. These include particularly exotic superconductors, strongly correlated electron systems, low dimensional spin systems and nanostructures. The pulse duration is sufficient for, for example, resistance, ultrasound and NMR measurements. In particular, can be used for magneto-optical experiments in the infrared spectrum the free-electron laser (FEL ) of the adjacent superconducting electron accelerator SAME.

HLD 2.0

Due to the large demand for experimental time, the HLD has been extended to 2013 and got six new cells pulse and a second capacitor bank.

Cooperations

The HLD cooperates with several research institutions in Dresden:

  • Max Planck Institute for Chemical Physics of Solids
  • Max Planck Institute for the Physics of Complex Systems
  • Technical University of Dresden
  • Leibniz Institute for Solid State and Materials Research Dresden
  • Leibniz Institute of Polymer Research Dresden

In addition to cooperation with other research institutions in Germany There is a European co-operation, which are funded by the European Union. The aim of the EU project "European Magnetic Field Laboratory ( EMFL ) " is to address new user for the large research facilities of the magnetic participating laboratories and to develop cooperation in management, infrastructure and communications. Involved are the EMFL the Dutch "High Field Magnetic Laboratory " in Nijmegen and the French " Laboratoire des Champs Magnétiques Intenses ( LNCMI ) in Grenoble and Toulouse.

The HLD is a member of the International Institute of Complex Adaptive Matter and (ICAM- I2CAM ).
