Descripción
Experiment QUIJOTE (Q-U-I JOint TEnerife) is a scientific collaboration,
leaded by the Instituto de Astrofísica de Canarias (IAC), which
can measure the polarization of the Cosmic Microwave Background (CMB) in
the range of frequency up to 200 GHz, at angular scales of 1°. The
project is composed of 2 telescopes and 3 instruments, located in Teide
Observatory (Tenerife, Spain). After the successful delivery of the
first telescope (operative since 2012), Idom is currently involved on
the turn key supply of the second telescope (phase II). The work started
in June 2013 and it will be completed in a challenging period of 12
months (operative at the beginning of July 2014), including design,
factory assembly and testing, transport and final commissioning on site.
This second unit will improve the opto-mechanical performance and
maintainability. The telescope will have an unlimited rotation capacity
in azimuth axis and a range of movement between 25°-95° in
elevation axis. An integrated rotary joint will transmit fluid, power
and signal to the rotary elements. The pointing and tracking accuracy
will be significantly below to specification: 1.76 arcmin and 44 arcsec,
respectively. This project completes Idoḿs contribution during
phase I, which also comprises the integration and functional tests for
the 5 polarimeters of the first instrument in Bilbao headquarters, and
the design and supervision of the building which protects both
telescopes, including the installation and commissioning of the
mechanism for shutters aperture.
