Abstract
DESHIMA 2.0 is an ultra-wideband submillimeter spectrometer based on integrated superconducting microstrip filters and Microwave Kinetic Inductance Detectors (MKIDs). We have successfully demonstrated its ultra-wideband performance in the laboratory. The measured instantaneous frequency coverage with ~300 MKIDs is 225-415 GHz, with a mean filter Q of ~670. The broadband quasi-optical chain of the instrument is characterized by beam patterns across the whole frequency range that are obtained simultaneously by a novel phase-amplitude beam measurement technique. We plan to deploy the instrument on the ASTE telescope for a commissioning and science verification campaign in 2022-2023.
