    • The Herschel SPIRE Instrument Dave Clements, Imperial College London Matt Griffin, SPIRE PI, Cardiff University Schloss Braunschardt 19/3/09
    • SPIRE – Far-IR Photometer and Spectrometer
      • SPIRE consists of two sub-instruments
      • A three colour far-IR Camera
      • Simultaneous images at 250, 350, 500 microns: first time these wavelengths have been explored from space
      • Also parallel mode with PACS
      • An imaging spectrometer
      • Wavelength range 200-670 microns: first spectral coverage from sapce
      • Simultaneous coverage of full wavelength range
      • For both sub-instruments detectors at 0.3K, optics and mechanisms at 2K and 5K
      The SPIRE Instrument | Dave Clements | Herschel | Pag. 2 > SPIRE undergoing lab testing
    • From cosmology to planet formation
      • What the Photometer Will do?
      • Cosmology
      • Find the missing 50% of energy generation in the universe
      • Galaxies evolve very differently in optical and far-IR, with many more far-IR bright objects early on, hiding 50% of energy generation. SPIRE will find and study them.
      • Star and Planet Formation
      • Star and planet formation is inherently dusty phenomenon
      • - SPIRE will find and determine properties of protostars and planetary debris disks
      The SPIRE Instrument | Dave Clements | Herschel | Pag. 2 > SPIRE’s scientific targets SPIRE/PACS
    • From cosmology to planet formation
      • SPIRE Spectrometer: Exploring molecules in space
      • Rich and largely unexplored range of spectral lines in far-IR/submm
      • SPIRE Spectrometer will provide our first chance to study this region
      • Look for water and CO lines
      • Look for complex organic molecules
      • Examine the mineralogy of interplanetary and intersteller dust
      • Survey instrument so not aimed at individual known lines so discovery potential is huge
      The SPIRE Instrument | Dave Clements | Herschel | Pag. 2 > SPIRE Spectrometer targets
    • Handy fact: The SPIRE Photometer can detect power of a 100W lightbulb a million km away - or a low energy bulb (20W) on the Moon. Herschel Blog: http://herschelmission.wordpress.com/ THANK YOU
