QUIJOTE Telescopes: QT1 and QT2
The layout of both QT1 and QT2 telescopes is based on an altazimuth mount supporting a primary (parabolic) and a secondary (hyperbolic) mirror disposed in an offset Gregorian Dracon scheme, which provides optimal polarization properties (polarization leakage ≤ -25dB), low sidelobes (≤-40 dB) and highly symmetric beams (ellipticity ≤ 2%). Each primary mirror has a 2.25m projected aperture, while the secondary has 1.89m. The system is under-illuminated to minimize side-lobes and ground spillover. Each telescope is mounted on its own platform that can rotate around the vertical axis at a maximum frequency of 6 rpm (i.e., 36 deg/s). QT1 was installed at the Teide Observatory in 2011, while QT2 was installed in 2014. On June 27th 2015, his Majesty the King of Spain inaugurated the two telescopes (QT1 and QT2) that make up the QUIJOTE experiment.
A complete description of the two telescopes can be found in Gomez et al. (2010) for QT1, and Sanquirce et al. (2014) ; Sanquirce-García et al. (2016) for QT2.
