Statements of Current States of the Art for Key non-Coronagraphic Technologies for HWO
Paul Scowen, Manuel Quijada, Emily Kan +7
In preparation for development of both key technologies and instrument concept studies to use those technologies, the Habitable Worlds Observatory Technology Maturation Project Off…
The Ultraviolet Type Ia Supernova CubeSat (UVIa): Science Motivation & Mission Concept
Keri Hoadley, Curtis McCully, Gillian Kyne +23
The Ultraviolet (UV) Type Ia Supernova Mission (UVIa) is a CubeSat/SmallSat concept that stands to test critical space-borne UV technology for future missions like the Habitable Wo…
Charge Coupled Device detectors with high quantum efficiency at UV wavelengths
Erika T. Hamden, April D. Jewell, Charles A. Shapiro +10
We report on multilayer high efficiency antireflection coating (ARC) design and development for use at UV wavelengths on CCDs and other Si-based detectors. We have previously demon…
Technology advancement of the CCD201-20 EMCCD for the WFIRST coronagraph instrument: sensor characterization and radiation damage
Leon K. Harding, Richard T. Demers, Michael Hoenk +15
The Wide Field InfraRed Survey Telescope-Astrophysics Focused Telescope Asset (WFIRST-AFTA) mission is a 2.4-m class space telescope that will be used across a swath of astrophysic…
Silicon Detector Arrays with Absolute Quantum Efficiency over 50% in the Far Ultraviolet for Single Photon Counting Applications
Shouleh Nikzad, Michael E. Hoenk, Frank Greer +8
We have used Molecular Beam Epitaxy (MBE)-based delta doping technology to demonstrate near 100% internal quantum efficiency (QE) on silicon electron-multiplied Charge Coupled Devi…
A system and methodologies for absolute QE measurements from the vacuum ultraviolet through the NIR
Blake C. Jacquot, Steve P. Monacos, Michael E. Hoenk +3
In this paper we present our system design and methodology for making absolute quantum efficiency (QE) measurements through the vacuum ultraviolet (VUV) and verify the system with…
UV anti-reflection coatings for use in silicon detector design
Erika T. Hamden, Frank Greer, Michael E. Hoenk +5
We report on the development of coatings for a CCD detector optimized for use in a fixed dispersion UV spectrograph. Due to the rapidly changing index of refraction of Si, single l…
Large Focal Plane Arrays for Future Missions
Paul A. Scowen, Shouleh Nikzad, Michael Hoenk +10
We outline the challenges associated with the development and construction of large focal plane arrays for use both on the ground and in space. Using lessons learned from existing…
