How dark the sky: the JWST backgrounds
Jane R. Rigby, Paul A. Lightsey, Macarena García Marín +17
We describe the sources of stray light and thermal background that affect JWST observations, report actual backgrounds as measured from commissioning and early-science observations…
Superfluid Liquid Helium Control for the Primordial Inflation Polarization Explorer Balloon Payload
A. Kogut, T. Essinger-Hileman, D. Fixsen +4
The Primordial Inflation Polarization Explorer (PIPER) is a stratospheric balloon payload to measure polarization of the cosmic microwave background. Twin telescopes mounted within…
The Balloon-Borne Cryogenic Telescope Testbed Mission: Bulk Cryogen Transfer at 40 km Altitude
A. Kogut, S. Denker, N. Bellis +3
The Balloon-Borne Cryogenic Telescope Testbed (BOBCAT) is a stratospheric balloon payload to develop technology for a future cryogenic suborbital observatory. A series of flights a…
Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging
Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13
Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
Sub-Kelvin cooling for two kilopixel bolometer arrays in the PIPER receiver
E. R. Switzer, P. A. R. Ade, T. Baildon +30
The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne telescope mission to search for inflationary gravitational waves from the early universe. PIPER employs tw…
Towards 100,000-pixel microcalorimeter arrays using multi-absorber transition-edge sensors
S. J. Smith, J. S. Adams, S. R. Bandler +15
We report on the development of multi-absorber transition edge sensors (TESs), referred to as hydras. A hydra consists of multiple x-ray absorbers each with a different thermal con…
