The cosmic microwave background (CMB) is microwave radiation from the Big Bang which permeates the entire observable universe. Inflation, a brief period of exponential expansion in the early universe, is predicted to have imprinted an extremely faint polarization signature, known as the …

LiteBIRD1 is a JAXA-led satellite mission planned for the 2030s to measure CMB polarization and search for the faint B-mode signal of inflation. Detecting this signal requires ultra-low-noise, polarization-sensitive TES bolometers read out with digital frequency-division multiplexing using LC filters and SQUID …

This work presents an array of 77 corrugated feed horns coupled with waveguide orthomode transducers (OMTs), operating in the 200−280 GHz band. The prototypes are realized in aluminum by combining the platelet and laser micro-machining techniques. Compared with more conventional approaches (Electroforming, …

The characterization of primordial B-mode polarization in the Cosmic Microwave Background (CMB) requires unprecedented control of instrumental systematic effects. One key effect are the thermal fluctuations induced by cosmic-ray (CR) interactions with cryogenic detectors. In this work, we present a numerical model …

Cosmic Microwave Background (CMB) polarization measurements are pushing instrumental sensitivities to levels where calibration systematics become a dominant limitation. The large dynamic range between cosmological and Galactic emission prevents future experiments from relying only on diffuse sky measurements or standard celestial calibrators. …
