In this paper we will describe the characterisation of a rf amplification chain based on a travelling wave parametric amplifier (TWPA). The detection chain is meant to be used for dark matter axion searches and thus it is mounted coupled to a high Q microwave resonant cavity. A system noise temperature T sys = (3 . 3 ± 0 . 1) K has been measured at a frequency of 10.77 GHz, using a novel scheme allowing measurement of T sys exactly at the cavity output port.

Widely tunable, nondegenerate three-wave mixing microwave device operating near the quantum limit.
The unprecedented accuracy with which the crossover between zero-point fluctuations and shot noise has been measured provides an upper bound for the noise and dissipation intrinsic to the device.
Observation of 4.2-K equilibrium-noise squeezing via a Josephson-parametric amplifier.
The authors observed the squeezing of 4.2 K thermal noise using a Josephson parametric amplifier operated in the degenerate mode at 19.4 GHz. A 42% reduction in the equilibrium noise was observed.
Revisiting the detection rate for axion haloscopes
The cavity haloscope has been employed to detect microwave photons resonantly converted from invisible cosmic axions under a strong magnetic field. In this scheme, the axion-photon conversion power
SQUID-based microwave cavity search for dark-matter axions.
The first result from such an axion search using a superconducting first-stage amplifier (SQUID) replacing a conventional GaAs field-effect transistor amplifier is reported, setting the stage for a definitive axions search utilizing near quantum-limited SQUID amplifiers.
Axion Search with a Quantum-Limited Ferromagnetic Haloscope.
The scientific run of the ferromagnetic axion haloscope resulted in the best limit on dark matter axions to electron coupling constant in a frequency span of about 120 MHz, corresponding to the axion-mass range 42.4-43.1  μeV.
