Abstract:
The Microwave SQUID Multiplexer (μMUX) is the device of choice for the readout of a large number of low-temperature detectors in a wide
variety of experiments within the fields of astronomy and particle physics. While it offers large multiplexing factors, the system noise perfor-
mance is highly dependent on the cold- and warm-readout electronic systems used to read it out, as well as the demodulation domain and
parameters chosen. In order to understand the impact of the readout systems in the overall detection system noise performance, first, we
extended the available μMUX simulation frameworks, including additive and multiplicative noise sources in the probing tones (i.e., phase and
amplitude noise), along with the capability of demodulating the scientific data, either in the resonator’s phase or the scattering amplitude.
Then, considering the additive noise as a dominant noise source, the optimum readout parameters to achieve minimum system noise were
found for both open-loop and flux-ramp demodulation schemes in the aforementioned domains. Later, we evaluated the system noise sensi-
tivity to multiplicative noise sources under the optimum readout parameters. ... mehr
