An Haloscope Amplification Chain based on a Travelling Wave Parametric Amplifier

Abstract

In this paper we will describe the characterisation of a rf detection 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 $T_{\mathrm{sys}}=(3.3\pm 0.1$) K has been measured at a frequency of 10.77 GHz, using a novel scheme allowing measurement of $T_{\mathrm{sys}}$ exactly at the cavity output port.
