Description
Over the past year, the proposal to build a high-frequency Small Aperture Telescope (SAT) to add to the Simons observatory has gradually become more and more consolidated. This project named Kairos is currently submitted for funding to the RI2 CNRS program (Recherche à risque et à impact) and has obtained the support of three institutes (IN2P3, INSU and INP). We propose to deploy a focal plane of about 30k LEKID detectors to observe the sky in two bands centered at 280 GHz and 340 GHz taking care of all the different sub-systems within the french collaboration. Adding a high frequency SAT to the pre-existing SATs will allow us to answer the outstanding question of mapping the polarized emission of interstellar dust with great sensitivity giving to the whole project a more precise measurement of the contamination of galactic dust emissions which currently constitutes one of the most limiting factors for CMB B-mode observations. We will present from a general point of view the instrumental configuration we propose to implement.
