“Creating Solid-State X-ray Cameras for Ultrafast Imaging at One Billion Frames per Second"

 

 

 

Abstract: 

High-speed X-ray cameras are powerful tools for visualizing complex plasma, shock, and material dynamics.  Experiments in the fields of High Energy Density (HED) science and Inertial Confinement Fusion (ICF) are generally transient non-repetitive events that require single-shot cameras for capturing multiple images on timescales of a nanosecond or less.  And arrays of synchronized cameras oriented at different viewing angles are required for tomographic reconstruction of 3D dynamics for comparison with modern numerical simulations.  We have developed a family of solid-state imaging sensors based on complementary metal-oxide-semiconductor (CMOS) technology for burst-mode x-ray imaging of HED and ICF experiments.  Our cameras utilize the same microelectronics technology that has revolutionized consumer photography and enabled sensors to be embedded into a growing number of everyday products.  The ease of use, small size, and low-cost of CMOS camera technology offers the potential for transforming ultrafast photography.  In this talk, I will describe the technology, physics and engineering challenges, initial applications, and our plans for faster speeds, increased numbers of imaging frames, and detection of higher energy x-rays and particles in future generations of sensors.
