PRIMA

The PRobe far-Infrared Mission for Astrophysics, PRIMA (PI: J. Glenn), is a cryogenically cooled far-infrared observatory with a diameter of 1.8 m. PRIMA has recently been selected for Phase-A study by NASA. 

PRIMA’s current design includes two science instruments: 

• FIRESS: a powerful, multi-mode survey spectrometer covering wavelengths between 24 and 235 micrometer with two different spectral modes: a low-resolution mode with R =100 and a high-resolution FTS mode, which offers tunable spectral resolution up to R = 4400 at 112 um and 20 000 at 25 um.

• PRIMAger is a multi-band spectrophotometric imager that offers hyperspectral linear variable filters in two bands (R = 10, PHI1 and PHI2) from 24 to 80 um together with polarimetric capabilities in four broadband filters (PPI) between 80 and 261  m.
