“…In addition, the electron-phonon coupling can be enhanced to some extent by optimizing the geometry of the junction array and increasing the volume of the metallic islands between the junctions. Therefore, additional metal cooling fins of sufficient volume have been widely utilized in various CBT designs [8][9][10].…”

“…However, both MAR and Shapiro measurements do not provide direct access to the effective electronic temperature of the system. The latter can be determined via primary thermometry, including the analysis of the Johnson-Nyquist 57,58 or shot-noise 59 of a calibrated sample resistor or Coulomb blockade spectroscopy 3,30,60 among other techniques, 61,62 which can be used to determine the absolute sample temperature.…”

Low-temperature electronic transport measurements with high energy resolution require both effective low-pass filtering of high-frequency input noise and an optimized thermalization of the electronic system of the experiment. In recent years, elaborate filter designs have been developed for cryogenic low-level measurements, driven by the growing interest in fundamental quantum-physical phenomena at energy scales corresponding to temperatures in the few millikelvin regime. However, a single filter concept is often insufficient to thermalize the electronic system to the cryogenic bath and eliminate spurious high frequency noise. Moreover, the available concepts often provide inadequate filtering to operate at temperatures below 10 mK, which are routinely available now in dilution cryogenic systems. Herein we provide a comprehensive analysis of commonly used filter types, introduce a novel compact filter type based on ferrite compounds optimized for the frequency range above 20 GHz, and develop an improved filtering scheme providing adaptable broad-band low-pass characteristic for cryogenic low-level and quantum measurement applications at temperatures down to few millikelvin.
