Abstract:
With this contribution we show the readout electronics for kinetic inductance detec-
tors (KIDs) that we are developing based on commercial IQ transceivers from
National Instruments and using a Virtex 5 class FPGA. It will be the readout elec-
tronics of the COSmic Monopole Observer (COSMO) experiment, a ground based
cryogenic Martin–Puplett Interferometer searching for the cosmic microwave back-
ground spectral distortions. The readout electronics require a sampling rate in the
range of tens of kHz, which is both due to a fast rotating mirror modulating the
signal and the time constant of the COSMO KIDs. In this contribution we show
the capabilities of our readout electronics using Niobium KIDs developed by Paris
Observatory for our 5 K cryogenic system. In particular, we demonstrate the capa-
bility to detect 23 resonators from frequency sweeps and to readout the state of each
resonator with a sampling rate of about 8 kHz. The readout is based on a finite-state
machine where the first two states look for the resonances and generate the comb of
tones, while the third one performs the acquisition of phase and amplitude of each
detector in free running. Our electronics are based on commercial modules, which
brings two key advantages: they can be acquired easily and it is relative simple to
write and modify the firmware within the LabView environment in order to meet the
needs of the experiment.
