For speed and coverage in deep
surveys, the design of the SPST telescope pursues an optimization
strategy:
- Build a reflector whose beamsize is equal to the spatial scale of
interest.
- Make the telescope losses, blockage, and spillover as small as
possible at the frequencies of interest.
- Make the field of view as large as possible.
- Populate that field of view with as many broadband detectors as
possible.
- Place that telescope at the best possible site.
This assures that the SPST is an "optimal design" for the
discovery of objects at spatial frequencies near 8 m/l,
such as S-Z effect from high redshift clusters and inter-cluster
filaments. |
