Future cosmic microwave background (CMB) experiments will be focused on the
study of the B-mode signal, which requires large number of detectors, very
good sensitivity and polarization selectivity. Kinetic Inductance Detectors
(KIDs) [1], based on superconducting resonators, are the ideal candidates to
be used in this type of experiments as they exhibit very good sensitivity and
they are intrinsically multiplexable which allows to couple thousands of
pixels to a single transmission line. However, further developments are still
needed for its use in future space missions. Among them, the development of
new materials for the detection of lower frequencies and the design of new
geometries for improving the polarization sensitivity are two key aspects that
should be improved.
In this work, I will briefly review the principle of operation of a KID based
on the BCS theory. Also, I will present our efforts on developing this type of
superconducting detectors which includes nanofabrication and low temperature
characterization. Finally, I will present our collaboration in the NIKA2
camera [3] installed at the 30 m telescope of IRAM-Granada and the KISS
spectrometer to be installed in the following months in the QUIJOTE telescope
in Tenerife. _
