Descripción
SPIRE, the Spectral and Photometric Imaging Receiver, is a submillimetre
camera and spectrometer for the European Space Agency's Herschel Space
Observatory. It comprises a three-band imaging photometer operating at
250, 360 and 520 μm, and an imaging Fourier Transform Spectrometer
(FTS) covering 200-670 μm. The detectors are arrays of
feedhorn-coupled NTD spider-web bolometers cooled to 0.3 K. The
photometer field of view of is 4 x 8 arcmin., observed simultaneously in
the three spectral bands. The FTS has an approximately circular field of
view with a diameter of 2.6 arcmin., and employs a dual-beam
configuration with broad-band intensity beam dividers to provide high
efficiency and separated output and input ports. The spectral resolution
can be adjusted between 0.04 and 2 cm-1 (resolving power of 20-1000 at
250 μm). The flight instrument is currently undergoing integration
and test. The design of SPIRE is described, and the expected scientific
performance is summarised, based on modelling and flight instrument test
results.
