Abstract:
Neutrino mass estimation experiments and cosmic microwave background (CMB)
radiation surveys both employ low-temperature detectors (LTD) known as calorim-
eters and bolometers, respectively. These detectors operate typically between 10
and 300 mK. LTDs multiplexed by means of a microwave superconducting quan-
tum interference device multiplexer (μMUX) demonstrated to be an excellent device
for the readout of several detectors in the microwave region. This entails generat-
ing a multi-tonal signal and its subsequent readout. A single-tone detection method
based on a Goertzel filter bank (GFB) channelizer was used for the readout of the
aforementioned signal, implemented in a software-defined radio readout architecture
within a field-programmable gate array. The measurements presented here demon-
strate remarkable results in validating the suitability of the GFB channelizer for this
system.
