We propose, design and construct a variant of the conventional axion haloscope concept
that could be competitive in the search for dark matter axions of masses in the decade 10 …

A bstract RADES (Relic Axion Detector Exploratory Setup) is a project with the goal of
directly searching for axion dark matter above the 30μeV scale employing custom-made …

We present a cryogenic microwave noise source with a characteristic impedance of 50 Ω,
which can be installed in a coaxial line of a cryostat. The bath temperature of the noise …

As the Atacama Large Millimeter/submillimeter Array (ALMA) nears completion, 73 dual-
polarization receivers have been delivered for each of Bands 3 (84-116 GHz) and 6 (211 …

This paper describes a waveguide hybrid-coupled multiplexer for frequencies around 400
GHz. The designed multiplexer has three bands with 25-GHz bandwidth and no frequency …

The turnstile junction exhibits very low cross-polarization leakage and is suitable for low-
noise millimeter-wave receivers. For use in a cryogenic receiver, it is best if the orthomode …

The axion is a well-motivated cold dark matter (CDM) candidate first postulated to explain
the absence of CP violation in the strong interactions. CDM axions may be detected via their …

The article is concerned with the experimental evidence that proves technical feasibility of
the hybrid planar integration (HPI) scheme that has been proposed to construct …

We present design and evaluations of a submillimeter double-ridged waveguide ortho-mode
transducer (OMT) for ALMA Band 8 (385–500 GHz) cartridge receiver. The measured …

We present the design and results of characterization of a new sideband separating (2SB)
mixer for 800-950 GHz, based on superconductor-insulator-superconductor (SIS) junctions …
