摘要：

Recently several approaches have been made to simplify the readout scheme of the standard de SQUID. A Double Relaxation Oscillation SQUID(DROS) consisting of a hysteretic de SQUID and a reference junction in series shunted by an inductor and a resistor can provide a very large flux-to-voltage transfer coefficient. Thus, a DROS with direct readout with room temperature de amplifier can be a good candidate for the next-generation SQUID magnetometer. We report on the development of a 3-channel magnetometer system based on DROS. The DROS is based on Nb/AlOx/Nb Josephson junctions and the main feature of the system is its simple readout electronics.
