A system for the precise measurement of electrical quantities by means of the root-mean-square (RMS) value of ac voltages or currents is described. The system is based on a planar multijunction thermal converter (PMJTC) and low-cost electronic components. The miniboard circuitry can also be used in several experiments where flexibility is required. As a first application, the system can carry out...
A system for the precise measurement of electrical quantities by means of the rms value of ac voltages or currents is described. The system is implemented by a multijunction thermal converter and low cost electronic circuits. As a first application the system can both carry out ac voltage comparisons and ac and dc voltage measurements.
Overdamped Nb/Al-AlOx/Nb Josephson junctions are an intermediate state between the SIS and SNS Josephson junctions. With a proper choice of the fabrication parameters, stable and reproducible nonhysteretic current-voltage characteristics have been obtained Featuring critical current densities up to 70 kA/cm2 and characteristic voltages up to 450 muV at 4.2 K, overdamped junctions are suitable for...
