Development of X-Ray Streak Camera with Large Dynamic Range and High Temporal-Spatial Resolution
To satisfy the diagnosis requirement of laser driven inertial confinement fusion (ICF), an X-ray streak camera system with large dynamic range and high temporal-spatial resolution is developed. By optimizing the design of electronic optics, improving the production process of streak image converter tube, as well as producing and using the efficient devices, we improve the dynamic range and temporal-spatial resolution of the streak camera. The photocathode working length of the camera is designed to be 30 mm, and the focus voltage is designed to be 12 kV. Static and dynamic calibration systems are set up with the help of femtosecond and picosecond lasers. The results show that the spatial resolution of the camera system is greater than 20 lp/mm, the temporal resolution reaches 5 ps, the dynamic range reaches 2237∶1, and the sweep speed nonlinearity is smaller than 3%. Ultra-fast signals can be achieved by four gears of the camera with four sweep speeds. The camera has good performance and can be used for precise diagnosis of temporal-spatial and energy spectrum resolution in laser fusion research.
