Simple Improved Reference Subtraction for H4RG, H2RG, and H1RG Near-infrared Array Detectors
Bernard J. Rauscher, Dale J. Fixsen, Gregory Mosby
Teledyne's H4RG, H2RG, and H1RG near-infrared array detectors provide reference pixels embedded in their data streams. Although they do not respond to light, the reference pixels e…
JWST NIRSpec's Cosmic Ray Experience at L2
Bernard J. Rauscher, D. J. Fixsen
We characterize cosmic ray interactions in blanked-off \JWST NIRSpec ``dark'' exposures. In its Sun/Earth-Moon L2 halo orbit, \JWST encounters energetic ions that penetrate NIRSpec…
The Primordial Inflation Explorer (PIXIE): Mission Design and Science Goals
Alan Kogut, Eric Switzer, Dale Fixsen +14
The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission concept to measure the energy spectrum and linear polarization of the cosmic microwave background (CMB). A si…
High-sensitivity transition-edge-sensed bolometers: improved speed and characterization with AC and DC bias
Logan Foote, Michael D. Audley, Charles +12
We report on efforts to improve the speed of low-G far-infrared transition-edged-sensed bolometers. We use a fabrication process that does not require any dry etch steps to reduce…
Systematic error mitigation for the PIXIE Fourier transform spectrometer
A. Kogut, Dale Fixsen, Nabila Aghanim +11
The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission concept to measure the spectrum and polarization of the cosmic microwave background. Cosmological signals are…
Characterization of Low-noise Backshort-Under-Grid Kilopixel Transition Edge Sensor Arrays for PIPER
Rahul Datta, Sumit Dahal, Eric R. Switzer +8
We present laboratory characterization of kilo-pixel, filled backshort-under-grid (BUG) transition-edge sensor (TES) arrays developed for the Primordial Inflation Polarization Expl…
