WSPEC: A waveguide filter-bank focal plane array spectrometer for millimeter wave astronomy and cosmology
Sean Bryan, James Aguirre, George Che +9
Imaging and spectroscopy at (sub-)millimeter wavelengths are key frontiers in astronomy and cosmology. Large area spectral surveys with moderate spectral resolution (R=50-200) will…
BFORE: The B-mode Foreground Experiment
Michael D. Niemack, Peter Ade, Francesco de Bernardis +19
The B-mode Foreground Experiment (BFORE) is a proposed NASA balloon project designed to make optimal use of the sub-orbital platform by concentrating on three dust foreground bands…
WSPEC: A Waveguide Filter Bank Spectrometer
George Che, Sean Bryan, Matthew Underhill +7
We have designed, fabricated, and measured a 5-channel prototype spectrometer pixel operating in the WR10 band to demonstrate a novel moderate-resolution (R=f/Δf~100), multi-pixel,…
A Compact Filter-Bank Waveguide Spectrometer for Millimeter Wavelengths
Sean Bryan, George Che, Christopher Groppi +2
We present the design and measurements of a 90GHz prototype of a millimeter-wave channelizing spectrometer realized in rectangular waveguide for astronomical instrumentation. The d…
