Conclusions

Archeops is a balloon-borne experiment, designed to measure the CMB anistropies from large (about 10 degrees) to small angular scales (about 10 arcminutes). Archeops is also a testbed for Planck HFI, and will provide useful information on galactic dust and point source polarisation. The balloon has already flown twice successfully: once during a test flight and another time for its first scientific flight from Kiruna. The first scientific flight yielded 7.5 hours of scientific data, with 14 detectors dedicated to CMB measurements. Results from this flight will come soon, and we showed that it will give good constrains on large angular scale, but less constraining on small angular scale due to the short duration of the flight. Archeops will fly again this Winter, in order to increase the accuracy on large scales and measure the small scales.
