The goal of the PolarKID project is testing a new method for the measurement of polarised sources, in order to identify all the possible instrumental systematic effects that could impact the detection of CMB B-modes of polarisation. It employs the KISS (KIDs Interferometer Spectrum Survey) instrument coupled to a sky simulator and to sources such as point-like black bodies (simulating planets), a dipole (extended source) and a polariser. We use filled-arrays Lumped Element Kinetic Inductance Detectors (LEKIDs) since they have multiple advantages when observing both in photometry and in polarimetry configuration.
