Presentation Transcript

  1. PureB detector • UV radiation and low-energy electrons • PureB detectors – high sensitivity for UV radiation and low-energy electron detection Electron range for Si Attenuation length in Si

  2. JPL also uses detectors with monolayer of boron!! • https://authors.library.caltech.edu/50955/1/386595.pdf

  3. PureB detector • Available dimensions of Al entrance windows • 1×1, 10×10, 50×50, 100×100, 300×300, 500×500 μm2 • 1×1, 10×10 mm2 • Field of view ?: • Earth • Space • IV characteristics – temperature sensor?? Low temperature IV characteristics

  4. Responsivity (1) • Responsivity in EUV and DUV range • Electron signal gain:

  5. Responsivity (2) • Responsivity in EUV and DUV range • Entrance window design for filtering undesired wavelengths

  6. Entrance window • Low energy PureB electron detector • Al used as an entrance window • No optical illumination • Beryllium window ? • UV detector • PureB used as an entrance window to filter the undesired wavelengths? • Choice of other materials suitable as an entrance windows ?? • Solar blind ??

  7. Radiation detection – earth (1) • Problem! • Earth imaging • Ozone layer between 10-50 km • Absorbs UV between 200 and 300 nm !! • Limited use for UV Earth imaging • Ozone layer monitoring ?? • Below 200 nm wavelengths detection ??

  8. Radiation detection – earth (2) • Applications:

  9. Radiation detection – space (1) • Cubesat UV detectors could be looking towards space • More applications for UV detection • Benefit: cubesat is outside the ozone layer so it can detect UV radiation more easily • Problem: detection and analysis would require spectrometer! • Workaround: PureB detectors designed to select single wavelength by entrance window design ?? • Feasibility of a UV imager onboard a Cubesat platform • https://orbi.uliege.be/bitstream/2268/194725/1/Feasibility%20of%20a%20UV%20imager%20onboard%20a%20Cubesat%20platform%20-%20C.%20Kintziger.pdf

  10. Radiation detection – space (2) • Applications:

  11. Radiation detection – space (3) • Meteor spectral features:

  12. Radiation detection – space (4) • Applications:

  13. Radiation detection – space (5)

  14. Particle detection (1) • Radiation belts – Van Allen radiation belts: • Earth's two main belts extend from an altitude of about 500 to 58,000 kilometers • The belts trap energetic electrons and protons. Other nuclei, such as alpha particles, are less prevalent

  15. Particle detection (2) • Applications:

  16. Particle detection (3) • Applications:

  17. Particle detection (4) • PureB detectors could be used to build REPTile detector:
