Paper Abstract

X-ray framing cameras (XFC) based on an ultra-high speed gated microchannel plate (MCP) as a routine diagnostic in laser-driven Inertial Confinement Fusion (ICF) experiment have deployed on domestic facility for several years, typically, these XFC devices used a normal MCP with 500μm thick and 12μm pore size, and achieved an optical temporal gate leas than 100 picoseconds, but which are vulnerable to suffer a time broadened temporal response when encounter heavy expose, due to the limited dynamic range of the normal MCP. We developed a 56mm format MCP with 250μm thickness and 6μm pore diameter, which objective is to promote the optical temporal gate and dynamic range for the upgrade XFC, this MCP is fabricated by a special designed low resistance glass, the reduced thickness, small pore size and increased gain linearity, offered which with ultra-fast temporal response and extended dynamic range characters. In this paper, we review the mechanisms that limiting the temporal response and gain linearity of this ultra-high speed gated MCP applied to XFC, and describe the design principle and development work of this ultra-fast temporal response, extended dynamic range and larger format MCP, this MCP will assemble to the upgrade XFC which is designed by CAEP and is currently in the final design stages.
