Reducing current noise in cryogenic experiments by vacuum-insulated cables
E. Mykkänen, J. S. Lehtinen, A. Kemppinen +4
We measure the current noise of several cryogenic cables in a pulse tube based dilution refrigerator at frequencies between about 1~mHz and 50~kHz. We show that vibration-induced n…

Improved Calibration of Instruments for Small Direct Currents
Hansjörg Scherer, Dietmar Drung, Christian Krause
We report on new calibration methods for picoammeters and low-current sources. The "Ultrastable Low-noise Current Amplifier" (ULCA) was used for the exemplary calibration of commer…
