Cet article décrit le développement de mélangeurs supraconducteur-isolant-supraconducteur (SIS) pour le grand réseau millimétrique/submillimétrique d'Atacama (ALMA) du point de vue du dispositif. Au cours de la phase de construction d'ALMA, l'Observatoire astronomique national du Japon (NAOJ) a fabriqué avec succès des mélangeurs SIS répondant aux exigences strictes de température de bruit d'ALMA, inférieure à 230 K (5 fois le bruit quantique) pour la bande 10 (787-950 GHz) en collaboration avec l'Institut National des Technologies de l'Information et de la Communication. La bande 10 couvre la bande de fréquences la plus élevée d'ALMA et est reconnue comme la bande la plus difficile en termes de technologie supraconductrice. Après la construction, le NAOJ a commencé les études de développement pour l'amélioration d'ALMA, telles que les mélangeurs SIS à large bande et multifaisceaux, conformément aux exigences scientifiques de haut niveau, qui sont également présentées.

Abstract: This paper describes the development of superconductor-insulator-superconductor (SIS) mixers for the Atacama Large Millimeter/submillimeter Array (ALMA) from the device point of view. During the construction phase of ALMA, the National Astronomical Observatory of Japan (NAOJ) successfully fabricated SIS mixers to meet the stringent ALMA noise temperature requirements of less than 230 K (5 times the quantum noise) for Band 10 (787-950 GHz) in collaboration with the National Institute of Information and Communications Technology. Band 10 covers the highest frequency band of ALMA and is recognized as the most difficult band in terms of superconducting technology. After the construction, the NAOJ began development studies for ALMA enhancement such as wideband and multibeam SIS mixers according to top-level science requirements, which are also presented.
