The soft X-ray picosecond framing camera based on the gated microchannel plate (MCP-XPFC) is a type of ultra-fast diagnostic tool that applied widely for ICF and plasma researches.By using the uniform design
a temporal-resolved regression equation of MCP-XPFC was presented.The analytic emphasis is the interaction of the gating electric pulse's width and amplitude on the temporal resolution.The temporal resolution of camera was computed by the gating theoretic model and the regression equation respectively
and measured by femtosecond laser system on the base of two groups parameters
the gating electric pulses applied on the micro-strip lines of the MCP-XPFC with
V1(t)
(250ps
1200V) and
V2(t)
(170ps
1400V).At last
the theoretic and experimental error was analyzed.The optimized voltage range are 800~1200V for electric pulse of 250 ps and 1100~1200V for electric pulse of 170ps.
