The Science Goals of the 7-Element Array

• Positive detection of CMB polarisation in the
  l-space region of 1500
• Characterisation of the CMB polarisation power
  spectrum over the l-space range 800-3000
• Detect (or more likely, set an upper limit to)
  the B-field

Details

• Assuming 7 antennas, 60 cm dia, 70 efficient,
  close-packed.
• 16 GHz Bandwidth 100 K Tsys.
• Achieve 1s (10 mK) in 1.6 hrs, single pointing.
• 8 8 degree mosaic (good l-space resolution) has
  400 pointings 2 months observing.
• (plus 4 months to demonstrate that the system is
  working)
• (plus another 4 months for bad weather, etc)
