Effects of the vibrations and electromagnetic pollution induced by a closed-cycle pulse-tube cryostat on high-accuracy electrical measurements
Mathieu Taupin, Kamel Dougdag, Djamel Ziane +1
A paradigm shift in achieving (sub-)Kelvin environments is currently underway with the democratization of cryogen-free cryocoolers. This transition is driven by their user-friendly…

Measuring Non-linearity in AH 2700A Capacitance Bridges with sub-ppm level uncertainty
Almazbek Imanaliev, Olivier Thévenot, Kamel Dougdag +1
The stability and non-linearity of a commercial AH 2700A capacitance bridge were studied beyond its specified capabilities using the Thompson-Lampard Calculable Capacitor (TLCC) at…
