Lumped element kinetic inductance detectors for space applications
Résumé
Kinetic Inductance Detectors (KIDs) are now routinely used on ground-based telescopes. These large arrays, deployed in formats up to several kilopixels, exhibit state-of-the-art performance at millimeter (e.g. 120-300 GHz, NIKA and NIKA2) and sub-millimeter (e.g. 350-850 GHz, AMKID) wavelengths. We have studied in detail the interaction of ionizing particles (muons, alphas, x-rays) with KID arrays of hundreds of pixels designed for Cosmic Microwave Background observations. We have also set up a dedicated cryostat in which we reproduce typical observing conditions of a space-borne CMB observation. We will report the details and conclusions from a large number of measurements.
