Recent Progress on Framing Imaging at XIOPM and Its Application Prospect in HEDP

The gated framing cameras with picosecond temporal resolution and micrometre spatial resolution are the indispensable two-dimensional diagnostic instruments for inertial confinement fusion (ICF) and high-energy density physics (HEDP) research. This presentation will give a brief introduction about the latest research progress on framing imaging at XIOPM CAS and try to explore the possibility of using these gating cameras in HEDP research. To detect time-resolved Compton radiographic images, a dual MCP framing camera is developed, which is sensitive to photons with energies higher than 50 keV. The pulse dilation technology has been adopted to develop pulse dilation framing camera with a temporal resolution less than 10 ps. The exposure time of the image intensifier at visible light has also been shortened to 230ps. These techniques and cameras are applicable to the HEDP community for elucidating the properties and structure of HEDP matter. The possible schemes include using the framing camera as the detector of X-ray backlight radiography to obtain multiple time-resolved images within one shot or enhancing the signal-to-noise ratio via gating, etc.
