Realisation of a quantum current standard at liquid helium temperature with sub-ppm reproducibility
Stephen Giblin, Emma Mykkänen, Antti Kemppinen +7
A silicon electron pump operating at the temperature of liquid helium has demonstrated repeatable operation with sub-ppm accuracy. The pump current, approximately 168 pA, is measur…
Traceable Coulomb Blockade Thermometry
Ossi Hahtela, Emma Mykkanen, Antti Kemppinen +6
We present a measurement and analysis scheme for determining traceable thermodynamic temperature at cryogenic temperatures using Coulomb blockade thermometry. The uncertainty of th…
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…
