Abstract

We describe the receiver package for the ASHTROS mission: a 2-color 4-pixel THz superconducting receiver that targets a pair of ionized nitrogen fine-structure lines at 1.46 THz and 2.46 THz. The latter mixer will be able to operate at ~2.7 THz in order to observe HD. The design of the receiver package allows observations in both polarizations toward a source to maximize sensitivity. The receiver is operated near 6 K physical temperature using a mechanical cryocooler. A bank of low-power commercially sourced ASIC spectrometers are used to produce astronomy data.
