Fabrication and characterization of Nb/Al-AlN /Nb superconducting tunnel junctions
Alexey Pavolotsky, François Joint, Udupa Sujit Manjunatha +6
We report a Nb/Al-AlN /Nb superconducting tunnel junction process in which the AlN barrier is formed by plasma nitridation using a compact microwave electron-cyclotron-resonance (E…
3D-Structured Polyethylene Windows for Low-Loss Transmission in Wideband Cryogenic Terahertz Systems
François Joint, Igor Lapkin, Pierre-Baptiste Vigneron +10
We present the design, fabrication, and characterisation of a broadband vacuum window and infrared filter based on ultra-high molecular weight polyethylene (UHMWPE) for millimeter…
Wideband 67-116 GHz receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, V. Belitsky +43
ALMA has been operating since 2011, but has not yet been populated with the full suite of intended frequency bands. In particular, ALMA Band 2 (67-90 GHz) is the final band in the…
Wideband 67-116 GHz cryogenic receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, L. Testi +25
The Atacama Large Millimeter/sub-millimeter Array (ALMA) is already revolutionising our understanding of the Universe. However, ALMA is not yet equipped with all of its originally…
SEPIA - a new single pixel receiver at the APEX Telescope
V. Belitsky, I. Lapkin, M. Fredrixon +31
Context: We describe the new SEPIA (Swedish-ESO PI Instrument for APEX) receiver, which was designed and built by the Group for Advanced Receiver Development (GARD), at Onsala Spac…
Detection of 183 GHz water megamaser emission towards NGC 4945
Elizabeth Humphreys, Wouter Vlemmings, Violette Impellizzeri +5
Aim: The aim of this work is to search Seyfert 2 galaxy NGC 4945, a well-known 22 GHz water megamaser galaxy, for water (mega)maser emission at 183 GHz. Method: We used APEX SEPIA…
