Abstract
DESHIMA 2.0 is a spectrometer for astronomical applications targeting sources at sub-mm wavelengths from 240GHz to 720GHz. The design for its wide band Quasi-Optical system was presented in the previous works. In this work, the experimental validation of the beam pattern of the system at the lower end of its frequency band is presented. The measurement for the complete frequency band of the system is ongoing and will be presented at the conference.
