CLASS: The Cosmology Large Angular Scale Surveyor
Thomas Essinger-Hileman, Aamir Ali, Mandana Amiri +41
The Cosmology Large Angular Scale Surveyor (CLASS) is an experiment to measure the signature of a gravita-tional-wave background from inflation in the polarization of the cosmic mi…
Design and characterization of the Cosmology Large Angular Scale Surveyor (CLASS) 93 GHz focal plane
Sumit Dahal, Aamir Ali, John W. Appel +44
The Cosmology Large Angular Scale Surveyor (CLASS) aims to detect and characterize the primordial B-mode signal and make a sample-variance-limited measurement of the optical depth…
The Cosmology Large Angular Scale Surveyor
Kathleen Harrington, Tobias Marriage, Aamir Ali +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a four telescope array designed to characterize relic primordial gravitational waves from inflation and the optical depth to r…
A Compact Cryogenic Thermal Source for Detector Array Characterization
David T. Chuss, Karwan Rostem, Edward J. Wollack +5
We describe the design, fabrication, and validation of a cryogenically-compatible quasioptical thermal source designed to be used for characterization of detector arrays. The sourc…
SOFIA - HIRMES: Looking forward to the HIgh-Resolution Mid-infrarEd Spectrometer
Samuel N. Richards, Samuel H. Moseley, Gordon Stacey +48
The HIgh-Resolution Mid-infrarEd Spectrometer (HIRMES) is the 3rd Generation Instrument for the Stratospheric Observatory For Infrared Astronomy (SOFIA), currently in development a…
The Cosmology Large Angular Scale Surveyor (CLASS): 38 GHz detector array of bolometric polarimeters
John W. Appel, Aamir Ali, Mandana Amiri +41
The Cosmology Large Angular Scale Surveyor (CLASS) experiment aims to map the polarization of the Cosmic Microwave Background (CMB) at angular scales larger than a few degrees. Ope…
Gemini multi-conjugate adaptive optics system review II: Commissioning, operation and overall performance
Benoit Neichel, François Rigaut, Fabrice Vidal +30
The Gemini Multi-conjugate Adaptive Optics System - GeMS, a facility instrument mounted on the Gemini South telescope, delivers a uniform, near diffraction limited images at near i…
Fabrication of Feedhorn-Coupled Transition Edge Sensor Arrays for Measurement of the Cosmic Microwave Background Polarization
Kevin L. Denis, Aamir Ali, John W. Appel +11
Characterization of the minute cosmic microwave background polarization signature requires multi-frequency, high-throughput precision instrument systems. We have previously describ…
