The QUIJOTE experiment: project overview and first results
2015
QUIJOTE (Q-U-I JOint TEnerife) is a new
polarimeteraimed to characterize the polarization of the
Cosmic Microwave Backgroundand other Galactic and extragalactic signals at medium and large angular scales in the frequency range 10-40 GHz. The multi-frequency (10-20~GHz) instrument, mounted on the first QUIJOTE
telescope, saw
first lighton November 2012 from the Teide
Observatory(2400~m a.s.l). During 2014 the second
telescopehas been installed at this
observatory. A second instrument at 30~GHz will be ready for commissioning at this
telescopeduring summer 2015, and a third additional instrument at 40~GHz is now being developed. These instruments will have nominal sensitivities to detect the B-mode polarization due to the primordial gravitational-wave component if the tensor-to-scalar ratio is larger than r=0.05.
