| Popis: |
Electron-based diagnostics at the National Ignition Facility use Sandia’s Icarus sensors for ultrafast imaging. However, the electron detection performance of these sensors has remained mostly unknown. Previous work characterized the singulated Common Anode photodiode structure of the ”Furi” and ”Hippogriff” but did not include the Common Cathode photodiode structure of the Icarus. Using a fully fabricated Icarus sensor, we measured the cross-sectional geometries and modeled the expected performance; then, we measured the sensor’s EQE, quantum yield, and charge gain with an electron gun. These measurements were essential to understanding the space-charge limitations of the electron-based diagnostics that use them. |
