“…The emission wavelength depends on the electron beam energy and the period of the wiggler, and can be tuned from 4 up to 280 μm. 10 A constant 100 mV bias was applied to the gold-coated contacts deposited on the facets perpendicular to the magnetic field. The FEL light of constant intensity was directed into the VTI, and the The magnetic field is directed along the [001] direction.…”

In this paper, we report a correction to the model potential of the Ga acceptor in germanium, evidenced by high-magnetic-field photoconductivity measurements. We found that under high magnetic fields the chemical shift of the binding energy of Ga acceptors vanishes, contrary to the results given by the generally accepted theory. To fit our data, we found that the central-cell correction should contain a repulsive part (i.e., it must be bipolar), in contrast to the purely attractive screened point-charge potential widely used in the literature.

“…The Hochfeld-Magnetlabor Dresden (HLD) built at the Helmholtz-Zentrum Dresden-Rossendorf, Germany, is a user facility for pulsed magnetic fields, which opened its doors to users in 2007 [2]. Since that time, enormous effort has been undertaken to fulfil the diverse requests of an increasing number of users for demanding working conditions and challenging sample environments.…”

We report on the design and successful testing (up to 55 T) of a 60 T long-pulse (LP) magnet with a pulse duration of 1500 ms at the Hochfeld-Magnetlabor Dresden. This magnet has the capability of producing magnetic fields with time and homogeneity characteristics suitable to host specific-heat and nuclear magnetic resonance (NMR) experiments. We describe the development of a specific-heat probe for this magnet, which uses the quasi-adiabatic heat-pulse method and enables magnetocaloric-effect measurements. Furthermore, we report the implementation of a NMR setup, consisting of home-built probe and spectrometer. Both experimental devices were tested successfully in the LP magnet up to 31 and 44 T, respectively.
