For about 25 years, IPAG, LPSC,
Institut Néel
and IRAM have
collaborated on leading projects in millimetric astronomy and
cosmology. Our expertise in operating telescopes, cryogenics,
nanotechnologies, electronics and data analysis have enabled us to
carry out successful projects on ground (Diabolo, NIKA and NIKA2),
on balloon (Archeops) and satellite (Planck).
Kinetic Inductance Detectors (KID) are a new and promising
technology based on the inductance variation of a supra conductor
when it is irradiated by photons. While we already have two
instruments currently scanning the sky with arrays of 2,000 KIDs,
NIKA2 (IRAM 30m
telescope, Pico Veleta, Spain) and Concerto (APEX,
ESO, Chili), we are now able to build arrays of 8,000 of them.
Such resonators and their electronics are not only relevant for
astronomy but also for operating Qubits and to progress
toward quantum computing.
KIDs are embedded in complex cryogenic instruments. Our expertise
is also on designing and building such instruments, their associated
optics components and electronics, and to develop the end to end data
analysis chain.
