State of the art and future prospective of high performance streak cameras for laser fusion

Abstract

The streak cameras have very important applications in Inertial Confinement Fusion (ICF), including x-ray streak cameras and optical streak cameras. At present, they are still the core diagnostic devices with the highest temporal resolution in this field. This paper introduces the performance and characteristics of two main types of the streak cameras widely used in the field of laser fusion both domestic and international. They are equipped with coaxial electrode double-focus electron optics streak tube and bilamellar electron optics streak tube respectively. In terms of specifications of streak camera, the criteria of dynamic range of streak camera are emphasized, the dynamic range data of today's international high performance streak cameras are presented. The paper also introduces several important research progresses in the development of streak camera technologies, including advanced backlighting ultraviolet fiducial system, neutron radiation tolerant device and gated cathode technology.
