| Zusammenfassung | In measurements with cryogenic current comparators (CCCs), robustness against mechanical distortions is an issue. Sources of distortions are part of the experimental environment, efficient suppression is difficult. In a test setup, we intentionally applied mechanical vibrations to a CCC probe. In the 10 Hz to 3 kHz range, the frequency response of the SQUID detector's output signal was recorded for an integrative and an H∞-controller. When applying vibrations at fixed frequency, the stability of the SQUID's locking depended on the chosen controller, but an influence on the result of a 12.9 kΩ vs. 100 Ω resistance comparison was not found. |
