Abstract
The epoch of reionization spectrometer (EoR-Spec) is an instrument module that will be deployed in the Prime-Cam receiver on the Fred Young Submillimeter Telescope (FYST), which is a 6m off-axis telescope for the CCAT-prime facility. FYST is currently being built in the Atacama Desert in Chile at an altitude of 5600 m. With the Fabry-Perot interferometer (FPI), EoR-Spec will measure the 158 µm [CII] line intensity at redshifts from 3.5 to 8 (420 to 210 GHz), with the lower redshifts tracing star formation and higher redshifts tracing the late stages of reionization. An EoR-Spec module includes three monolithic and monochroic feedhorn-coupled arrays of kinetic inductance detectors (KIDs), two of which are centered at 260 GHz with the other centered at 370 GHz. We present the design and integration process of the EoR-Spec detector array at both bands. The 370 GHz detector array will consist of 3072 detectors and each of the 260 GHz arrays will consist of 1728 detectors. Each of the detector arrays contains an aluminum feedhorn array and is read out by a few pairs of coaxial cables.
