| Abstract: |
We describe the scientific goals and outline design for the SPIRE instrument to be launched on the ESA cornerstone mission FIRST. SPIRE is a bolometer instrument covering the wavelength rage 200-600 microns, and will have three imaging channels centred at approximately 250, 350 and 500 microns, along with a broad-band imaging Fourier transform spectrometer operating from 200-670 microns. The photometer will observe the same 4 x 8 arcminute field of view simultaneously in all three bands with diffraction-limited angular resolution (18 arcseconds at 250 microns). The spectrometer will have a field of view of 2.6 × 2.6 arcminutes and will have spectral resolution adjustable from approximately 20 to 1000. The detector arrays will operate at helium-3 temperature (0.3 K). The primary science goals of SPIRE are deep extragalactic and galactic surveys for high-redshift galaxies and young protostellar sources respectively, and follow-up spectrophotometric observations. |
