A Pixel Sensor Resolves 390-Electron-Volt Photons
A thin-window iLGAD sensor achieved single-photon resolution below the nitrogen K-edge with a signal-to-noise ratio of five.
Summary
A thin-window iLGAD sensor achieved single-photon resolution below the nitrogen K-edge with a signal-to-noise ratio of five.
Two gain-layer designs exposed a double-peak spectrum tied to absorption depth. A fitted model then estimated the entrance and gain-layer geometry, informing larger high-frame-rate soft-X-ray detectors.
Why it matters
A thin-window iLGAD sensor achieved single-photon resolution below the nitrogen K-edge with a signal-to-noise ratio of five.
Limits and context
No additional limitation was separately recorded.
Key claims
