The PERCIVAL detector: first user experiments

Area of Science:

• Soft X-ray science
• Photon science
• Advanced detector technology

Background:

• The PERCIVAL detector is a novel CMOS imager developed for soft X-ray applications.
• It is currently in the final stages of development but has undergone initial user experiments.

Purpose of the Study:

• To evaluate the performance of the PERCIVAL detector in real-world soft X-ray experimental conditions.
• To highlight the detector's suitability for various advanced imaging and spectroscopy techniques.

Main Methods:

• The detector was utilized in user experiments including ptychography at a free-electron laser, holographic imaging at a storage ring, and X-ray photon correlation spectroscopy.
• Performance was assessed based on spatial resolution, dynamic range, and frame rate.

Main Results:

• The PERCIVAL detector demonstrated excellent spatial resolution due to its small pixel size, large active area, and high dynamic range.
• It achieved significantly faster frame rates compared to traditional CCD detectors.

Conclusions:

• The PERCIVAL detector's combination of high spatial resolution, large dynamic range, and high frame rate makes it a highly attractive instrument for soft X-ray science.
• Its performance in initial user experiments validates its potential for advancing photon science research.
