A two-dimensional imaging enabled x-ray streak camera system

Streak cameras are powerful tools that provide high temporal resolution by capturing one-dimensional images with slitted photocathodes while sacrificing the two-dimensional spatial information. A two-dimensional imaging enabled x-ray streak camera system has been developed to acquire the two-dimensional images in situ, with 27 μm spatial resolution and 150 ps time resolution. By attaching a scintillator plate in front of the cathode, x-ray emissions beyond the cathode slit are converted into visible light and recorded by an imaging camera. The simultaneous measurement of one-dimensional time-resolved and two-dimensional time-integrated images in the laser fusion experiment has demonstrated the benefits of the endoscope. Such a system could greatly extend the uses of traditional x-ray streak cameras.
