Abstract

Novel facilities in a resistor calibration service are described. These facilities were tested in 1988-9 in practical work with the IMS (Institute for Metrological Service) resistance standard. As the highest accuracy quantized Hall effect (QHE) standard in the USSR, the IMS standard has been used to establish the ohm representation in the central industrial region of the USSR and in some of the Eastern European countries. The IMS stationary apparatus comprises 12-T/0.3 K and 12-T/1.2 K cryomagnetic systems, a group of reference resistors thermostabilized Hamon dividers, a set of high-mobility Si-MOSFETs and GaAs/AlGaAs heterojunctions, and automatic resistance comparators.<>
