The LSPE-Strip feed horn array
نویسندگان
چکیده
Abstract In this paper we discuss the design, manufacturing and characterization of feed horn array Strip instrument Large Scale Polarization Explorer (LSPE) experiment. is a microwave telescope, operating in Q- W-band, for observation polarized emissions from sky large fraction (about 37%) Northern hemisphere with sub-degree angular resolution. The focal plane populated by forty-nine Q-band six W-band corrugated horns, each feeding cryogenically cooled polarimeter detection Stokes Q U components signal sky. channel designed to accurately monitor Galactic synchrotron emission, while combination will allow study atmospheric effects at site, Observatorio del Teide, Tenerife. focus on development including design requirements, engineering manufacturing, as well detailed performance verification.

Multi-chroic Feed-Horn Coupled TES Polarimeters
Multi-chroic polarization sensitive detectors offer an avenue to increase both the spectral coverage and sensitivity of instruments optimized for observations of the cosmic-microwave background (CMB) or sub-mm sky. We report on an effort to adapt the Truce Collaboration horn coupled bolometric polarimeters for operation over octave bandwidth. Development is focused on detectors operating in bot...
متن کاملCell Morphing: From Array Programs to Array-Free Horn Clauses
Automatically verifying safety properties of programs is hard. Many approaches exist for verifying programs operating on Boolean and integer values (e.g. abstract interpretation, counterexampleguided abstraction refinement using interpolants), but transposing them to array properties has been fraught with difficulties. Our work addresses that issue with a powerful and flexible abstraction that ...
متن کاملFocal-Plane Array Architectures: Horn Clusters vs. Phased-Array Techniques
The science goals of the SKA specify a field of view which is far greater than what current radio telescopes provide. Two possible feed architectures for reflector antennas are clusters of horns or phased-array feeds. This memo compares these two alternatives and finds that the beams produced by horn clusters fall short of fully sampling the sky and require interleaved pointings, whereas phased...

This paper shows injection molded millimeter-wave horn array antenna for the 1-dimensional APAA(Active Phase Array Antenna). The antenna is composed of horn antennas, grooved circular waveguide polarizers, E-plane T-junctions, and E-plane bends employing dielectric waveguides. This structure makes it possible to manufacture a feed circuit and radiating elements as an integrated unit by using in...
