The TRISTAN detector. Cosmic ray survey between latitudes 38ºN and 53ºS along the Atlantic Ocean
Résumé
TRISTAN (TRasgo para InveSTigaciones ANtarticas) is a cosmic ray detector of the TRASGO
family. The detector has been installed at the Spanish Antarctic Base in Livignston Island, as one
of the detectors of ORCA (Antarctic Cosmic Ray Observaroty) in December 2019. TRISTAN
detector collected data during three journeys crossing the Atlantic Ocean between latitudes 38ºN
and 53ºS on board of the Sarmiento de Gamboa and BIO Hesperides oceanographic vessels. The
trips took place between November 2018 and December 2019. The main purpose is to evaluate
the capability of a TRASGO detector to explore the geomagnetic field variations and the different
atmospheric behaviours at both hemispheres and in the Equator region. The main technical aspects
of the detector and its performance (efficiency, resolutions, and acceptances) will be discussed
and the preliminary results of the last journey will be presente
