Sub-nanosecond single line-of-sight (SLOS) x-ray imagers (invited)

Area of Science:

• Physics
• Engineering
• Materials Science

Background:

• Advanced x-ray imaging is crucial for understanding complex high-energy phenomena.
• Existing diagnostic tools often lack the necessary temporal resolution for fast processes.

Purpose of the Study:

• To develop and characterize a new generation of fast-gated x-ray framing cameras.
• To achieve 30 picosecond (ps) temporal resolution for capturing dynamic x-ray emission.
• To provide advanced imaging capabilities for ICF and HED research.

Main Methods:

• Integration of pulse-dilation electron imaging technology.
• Utilization of burst mode hybrid-complementary metal-oxide-semiconductor (H-CMOS) sensors.
• System architecture design and optimization techniques for high performance.

Main Results:

• Successful development and fielding of two novel fast-gated x-ray framing cameras.
• Demonstrated capability for capturing multiple frames along a single line-of-sight.
• Achieved 30 ps temporal resolution, enabling detailed study of rapid x-ray events.

Conclusions:

• The developed fast-gated x-ray cameras represent a significant advancement in diagnostic capabilities for ICF and HED research.
• These instruments offer superior temporal resolution for capturing ultrafast x-ray phenomena.
• Future improvements will focus on further enhancing the design for even greater performance and versatility.
