By optimizing the bridge circuit design and temperature control algorithm, the AC Bridge Temperature Controller overcomes the challenges of high signal noise and slow control response in traditional cryogenic measurements. It provides excellent temperature measurement and control capabilities for dilution refrigerators (DRs) operating below 100 mK. It is particularly suitable for quantum device characterization scenarios that require long-term, stable maintenance of low temperatures in the mK range.
