The QUIJOTE experiment: project overview and first results
Abstract
QUIJOTE (Q-U-I JOint TEnerife) is a new polarimeter aimed to characterize the polarization of the Cosmic Microwave Background and 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 light on November 2012 from the Teide Observatory (2400 m a.s.l). During 2014 the second telescope has been installed at this observatory. A second instrument at 30 GHz will be ready for commissioning at this telescope during 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.
