Visit to the QUBIC Integration Laboratory
72nd anniversary of the CNEA
On June 8, after the act for the 72nd anniversary of the CNEA, a special visit was made for the guests and authorities of the CNEA who did not know the instrument. The tour was guided by Ing. Cristian Rodríguez, head of the Laboratory.

QUBIC featured in a special edition of the Journal for Cosmology and Astroparticle Physics
On April 21, 2022, a special edition of the Journal of Cosmology and Astroparticle Physics was published exclusively dedicated to QUBIC, with 8 articles that describe the instrumental concept, present the results of the laboratory tests on the operation of all its components and the scientific capabilities of the instrument.
The papers are available at the following links:
–Paper I: Overview and science program
–Paper II: Spectral polarimetry with bolometryc interfeometry
–Paper III: Laboratory characterization
–Paper IV: Performance of TES bolometers and redout electronics
–Paper V: Cryogenic system and design and performance
–Paper VI: Cryogenic half wave plate rotator, design and performance
–Paper VII: The freedhorn-switch system of the technological demonstrator
-Paper VIII: Optical design performance
October 26, 2021, 11:00 a.m. (ARG) – Inauguration of the QUBIC Integration Laboratory at CNEA Regional Noroeste.
With the presence of the Minister of Science, Technology and Innovation of the Nation, Lic. Daniel Filmus, the Minister of Education, Culture, Science and Technology of the Province of Salta, Mag. Matías Canepa, the President of the CONICET, Dr. Ana Franchi, Mrs. President of CNEA, Dr. Adriana Serquis and the representatives of the Board of Directors of QUBIC in Argentina, Drs. Alberto Etchegoyen and Gustavo Romero, the QUBIC Integration Laboratory was inaugurated.
This is a fundamental step for the installation of the instrument that seeks to analyze the traces of the primordial gravitational waves, which occurred 13,800 million years ago, linked to the moment of universal inflation.

QUBIC (Q-U Bolometric Interferometer for Cosmology) is an international project of experimental cosmology that aims to measure the B-mode in the polarization of microwave background radiation (CMB, for Cosmic Microwave Background), in order to discover what happened in the first moments after the birth of the Universe. Mode B of polarization would be related to primordial gravitational waves, predicted by the Inflationary Theory, a modification of the Big Bang Theory, which predicts an exponential expansion in the first moments of life of the Universe.
The project is carried out by an international collaboration that involves institutions from France, Italy, the United Kingdom, Ireland, the United States and the Argentine Republic. Our country was chosen as the site of the first instrument, which will be located in the Alto Chorrillos area, Salta Province, at 4,900 meters above sea level – a site that will also house the Argentine-Brazilian radio telescope LLAMA (Large Latin American Millimiter Array) -. In this way, the Argentine Northwest will become a center of scientific attraction at a national, regional and global level.
