Abstract
With the recent Astro2020 report, a NASA-led cryogenic far-IR probe has emerged as the primary opportunity for sensitive measurements between the 28-micron cutoff of JWST and the onset of ground-based windows in the submillimeter. The probe will provide new tools for topics ranging from star formation in the earliest galaxies, to the cosmic history of heavy elements, to the formation of stars and planets. We will present our work optimizing the scientific return from this powerful yet cost-capped mission. The instrumentation emphasizes spectrophotometry and spectroscopy, both wide-field and pointed. It will provide high-fidelity maps and unbiased redshift-resolved surveys, as well as rich, high-sensitivity spectra of targets of interest. Paramount among the design trades is that of spatial multiplexing vs spectral resolving power; this optimization is conducted in light of the multiple science goals, and within the constraints of realistic detector sensitivity and array format.
