Notes:
The design and construction of a low-losses coaxial double-slug tuner for impedance matching of a bimodal cavity resonator is described. Voltage-standing-wave-ratio values close to one were readily achieved and significant improvements in the cavity Q factor have been realized using this new coupler. Accurate microwave Hall mobility results have been obtained and 60% reduction in experimental time was possible. A decrease in resistive losses in the order of 2 dB enhanced the measurement sensitivity and the lower bound of the detectable mobility was also reduced to 2.5 cm2/V s.
