摘要：

A compact design of a combined cryogenic current comparator and null detector assembly is described. The system is intended for integration in a four-terminal resistance ratio bridge to provide both current ratio and voltage ratio balance. The comparator and null detector are contained within the same superconducting shield having an overall diameter of less than 50 mm. The assembly is suitable for use in a wide-neck liquid heliuim cryostat or can be integrated in a cryogen-free apparatus.
