PRIMA is a 1.8-m diameter, cryogenically-cooled to 4.5 K, far-infrared observatory concept for the community in the 2030 decade. PRIMA includes both a sensitive wideband spectrometer FIRESS, and a multi-band spectrophotometric imager / polarimeter PRIMAger. Both instruments use detectors limited by the natural background, and PRIMA’s sensitivity unlocks the potential of the far-IR waveband to advance astrophysics across a broad range of topics spanning from galaxy and dust evolution in the early universe to the formation of planets and planetary atmospheres.
FIRESS offers full-band instantaneous coverage from 24 to 235 μm in two modes. The low-res mode offers R~100 with long slits, while the high-resolution mode offers R up to 4,400 × (112 μm / λ) in smaller fields. PRIMAger offers rapid R=10 hyperspectral imaging with continuous coverage from 25 to 84 μm, and imaging polarimetry in 4 bands from 90 to 235 μm.
