Neutron Scattering at Highest Magnetic Fields at the Helmholtz Centre Berlin

HFM/EXED: The High Magnetic Field Facility for Neutron Scattering at BER II

“…It is a series-connected magnet system with an outer superconducting coil and two inner resistive coils Smeibidl et al, 2010). The total eld of 26.3 T is achieved with a 4 MW insert coil set, which has the potential to be upgraded to 8 MW and a total eld of 31 T. The magnet is designed taking into account the special geometric constraints of performing neutronscattering experiments.…”

“…HFM/EXED -the high magnetic eld facility for neutron scattering Figure 1 -consists of two main components: the High Field Magnet System (HFM) and the Extreme Environment Di ractometer (EXED) Peters et al, 2006;Prokhnenko et al, 2015;Smeibidl et al, 2010). The former is a continuous eld hybrid magnet, built by the HZB in collaboration with the National High Magnetic Field Laboratory, Tallahassee, FL, USA (NHMFL) (Smeibidl et al, 2016).…”

Materials and Life Science Experimental Facility at the Japan Proton Accelerator Research Complex III: Neutron Devices and Computational and Sample Environments

“…On the other hand, in spite of the importance of the magnetic field environments, if we plan to construct a steady higher magnetic field system, usually the strengths of those magnetic field environments are limited, because there is a technical problem about high electric power consumption, which means that running costs are high. Therefore, the typical accessible strengths of such conventional magnetic field equipment are approximately more than 10 and less than 20 T. Of course, a special dedicated higher steady magnetic field system of 26 T was constructed at Helmholtz-Zentrum Berlin (HZB, Berlin-Wannsee, Germany) [64,65].…”

Flexible sample environment for high resolution neutron imaging at high temperatures in controlled atmosphere

“…The hydrogen concentration can be full quantitatively determined if the dependence of the total neutron cross section on the hydrogen concentration is calibrated by means of samples with known concentration 4 or for in situ measurements as described in Ref. 19. This test was performed at BOA beamline at PSI.…”

“…13 for corresponding observations of the kinetics of many important processes including phase transitions and changes in microstructure and crystal structure or stress fields in materials under variable conditions. However, establishing in situ investigations of such processes in a neutron beam often requires specific sample environments like cryostats, 18 magnets, 19 or furnaces, 1,20 which add limitations to the acquisition of high quality data.…”
