Polarization THz spectroscopy in high pulsed magnetic fields in Voigt and Faraday geometries

The paper presents the design and the performance of a pulsed magnetic field system for quasi-optical polarization THz (100 - 1000 GHz) spectroscopy capable to obtain 50 T at room temperature in Voigt and Faraday geometries, using backward wave oscillators as radiation sources. The developed facility is compact and relatively cheap. This allows one to realize the spectroscopy in magnetic fields up to 50 T in scientific communities with restricted financial and personnel opportunities.
