Conclusions

  1. 1.

    When a device whose operation is based on effects in superconductors, is used, it is possible to construct a dc stabilizer with a long-term instability of 2.5·10−7 for 1 A; this value is not the limit if one takes into consideration the possible further improvement of superconducting quantum interferometers (SQI) and of the electronic equipment.

  2. 2.

    The range of the current amplitudes to be stabilized is at least 15 A for the particular type of superconducting quantum interferometer.

  3. 3.

    The proposed two-stage stabilization scheme guarantees an adjustment of the current to be stabilized within wide limits and an automatic adjustment to a selected current amplitude when the instrument is switched on repeatedly.

  4. 4.

    The current stabilizer can be used as current source for reproducing the ampere via the ohm and the volt, the weber, and the tesla; the current stabilizer can also be used for building high-quality references for measurements of the magnetic induction. Furthermore, the current stabilizer can be used for the precise comparison of dc currents.
