Readout and characterization system for kinetic inductance detectors (KID) of the MUSCAT project.
MUSCAT is a continuum millimetre camera for the 1.1 mm band. It consists of six arrays of 243 kinetic inductance detectors (KID) each, for a total of 1458 detectors. It operates at a temperature of 150 mK, using a novel closed-cycle cooling system. This camera belongs to the new generation of instru...

| Sumario: | MUSCAT is a continuum millimetre camera for the 1.1 mm band. It consists of six arrays of 243 kinetic inductance detectors (KID) each, for a total of 1458 detectors. It operates at a temperature of 150 mK, using a novel closed-cycle cooling system. This camera belongs to the new generation of instruments to be installed in the Large Millimeter Telescope (LMT). The LMT is the largest millimetre telescope in the world, with a 50 m primary reflector. It is located on the top of the extinct volcano Sierra Negra at 4600 m high in the Mexican state of Puebla. In the 1.1 mm band it is capable of reaching an angular resolution of up to 5.5". The development of KID detectors goes through a cyclical process of design, manufacturing, readout and characterization of their parameters. The final part of this cycle allows evaluating the performance of the detector according to the needs of the application, to suggest improvements in the design and repeat the process consequently. In this sense, because the trend in the development of the instruments points to the exponential increase in the number of detectors, as is the case of MUSCAT, the rapid and efficient characterization of all of them becomes essential, to accelerate the consolidation of the final detector design. In this thesis, I preset a characterization system that includes the readout and quantitativequalitative analysis of the response of the detectors array as a function of detector base temperature, incident optical power, and RF readout power. The readout system, called KID Lab/mux-channel, through the frequency multiplexing technique performs 1) the simultaneous acquisition of the RF transmission S₂₁ of the detectors for a given span and step size, where it accurately locates the resonance frequencies and on which the set of readout tones is adjusted to 2) initiate the parallel acquisition of the response of the detectors. From this information, the analysis tool, called KID Analyzer, extracts the physical parameters of the array and its detectors such as their resonance frequencies, quality factors, generation-recombination noise level (GR), the quasi-particles lifetime, responsivity, noise equivalent power (NEP), among others. Applying the above tools, I characterised the distribution and cross-talking between the 243 detectors of one of the full-size prototype array for MUSCAT, where it was observed that the individual response of most of the detectors is appropriate. |
