Second-generation Micro-Spec: A compact spectrometer for far-infrared and submillimeter space missions
Giuseppe Cataldo,Emily M. Barrentine,Berhanu Bulcha,Negar Ehsan,Larry Hess,Omid Noroozian,Omid Noroozian,Omid Noroozian,Thomas R. Stevenson,Edward J. Wollack,Samuel H. Moseley,Eric R. Switzer +11 more
TL;DR: MicroSpec as mentioned in this paper is a direct-detection spectrometer which integrates all the components of a diffraction-grating spectrometers onto a ≈ 10 -cm2 chip through the use of superconducting microstrip transmission lines on a single-crystal silicon substrate.
Journal ArticleDOI
Electromagnetic Design of Feedhorn-Coupled Transition-Edge Sensors for Cosmic Microwave Background Polarimetry
David T. Chuss,Charles L. Bennett,Nick Costen,Erik Crowe,Kevin L. Denis,Joseph Eimer,Nathan P. Lourie,Tobias A. Marriage,Samuel H. Moseley,Karwan Rostem,Thomas R. Stevenson,Deborah Towner,Kongpop U-Yen,George M. Voellmer,Edward J. Wollack,Lingzhen Zeng +15 more
TL;DR: In this paper, the authors describe the electromagnetic design of feedhorn-coupled, TES-based sensors, where each linear orthogonal polarization from the feed horn is coupled to a superconducting microstrip line via a symmetric planar orthomode transducer (OMT).

Transition-edge sensor detectors for the Origins Space Telescope
TL;DR: In this article, the applicability of transition-edge sensors, as both calorimeters and bolometers, to meet the requirements of the Origins Space Telescope was discussed, and a path toward improving the present state-of-the-art was laid out.
