  We have performed terahertz time-domain magnetospectroscopy by combining a
rapid scanning terahertz time-domain spectrometer based on the electronically
coupled optical sampling method with a table-top mini-coil pulsed magnet
capable of producing magnetic fields up to 30 T. We demonstrate the capability
of this system by measuring coherent cyclotron resonance oscillations in a
high-mobility two-dimensional electron gas in GaAs and interference-induced
terahertz transmittance modifications in a magnetoplasma in lightly doped
n-InSb.
