Characterization of the Percival detector with soft X-rays

Area of Science:

• Detector Physics
• X-ray Optics

Background:

• The Percival 2-Megapixel (P2M) detector is a novel back-side-illuminated imaging sensor.
• Characterization of such detectors is crucial for advancing scientific instrumentation.

Purpose of the Study:

• To present the back-side-illuminated Percival 2-Megapixel (P2M) detector.
• To characterize its performance using optical and X-ray photons, particularly soft X-rays (250 eV to 1 keV).
• To assess key performance parameters including noise, dynamic range, and single-photon discrimination.

Main Methods:

• Optical and X-ray photon characterization of the P2M detector.
• Measurement of noise, dynamic range, and single-photon response.
• Analysis of soft X-ray performance (250 eV - 1 keV).

Main Results:

• The paper details the first-time characterization of the P2M detector's response to soft X-rays.
• Key performance metrics such as noise, dynamic range, and single-photon discrimination capability were measured.
• Initial assessment of the detector's capabilities and limitations was performed.

Conclusions:

• The Percival 2-Megapixel (P2M) detector exhibits promising performance characteristics.
• The presented characterization provides valuable data for its application in scientific imaging.
• Limitations and future improvements for the P2M detector are discussed.
