LSPE/SWIPE is a balloon-borne experiment aimed at measuring the B-mode polarization of the cosmic microwave background (CMB) exploiting the reionization peak at ℓ<10, with the primary target of improving the tensor-to-scalar ratio limit down to r=0.03 at 99.7% confidence level. SWIPE will use 326 spider-web Ti/Au transition-edge sensor (TES) bolometers, realized at INFN Genova, hosted on two focal planes cooled down at 300 mK and readout by superconducting quantum interference devices (SQUIDs), with multi-mode horns to couple the instrument's optical stages to the detectors. We present our design and demonstration of a 16-channel frequency domain multiplexing (FDM) system to readout SWIPE's TES bolometers.

Abstract

LSPE/SWIPE is a balloon-borne experiment aimed at measuring the B-mode polarization of the cosmic microwave background (CMB) exploiting the reionization peak at ℓ<10, with the primary target of improving the tensor-to-scalar ratio limit down to r=0.03 at 99.7% confidence level. SWIPE will use 326 spider-web Ti/Au transition-edge sensor (TES) bolometers, realized at INFN Genova, hosted on two focal planes cooled down at 300 mK and readout by superconducting quantum interference devices (SQUIDs), with multi-mode horns to couple the instrument's optical stages to the detectors. We present our design and demonstration of a 16-channel frequency domain multiplexing (FDM) system to readout SWIPE's TES bolometers.
