Abstract

DESHIMA 2.0 is a sub-millimetre wave spectrometer based on a single superconducting chip with a large instantaneous bandwidth. The instrument consists of a Quasi-optical (QO) system and an on-chip filter-bank coupled to an array of Kinetic Inductance Detectors (KID). In this work, this broad band QO system, operating at sub-millimetre wavelengths (220 GHz to 720 GHz), will be presented. This design is achieved using a field matching technique and consists of a hyper-hemispherical leaky lens antenna coupled to a series of Dragonian reflectors. The optimized design has an average illumination efficiency over the band of ~70%. This performance is also measured directly through the response of the KIDs.
