Improvement of Space Construction and FOV Definition of MCP with Small Aperture by Gas Sinter Technology

Image intensifiers with high resolution are strict with the pore, space construction and FOV definition of microchannel plate (MCP) with a large number of experiments, we extended progress in the MCP making technique and then fabricated some MCPs whose pores are 6μm and pitches are 8μm. Comparing our MCPs with the MCPs delivered by Photonis Company, we found the rosettes in our MCPs are less than the ones in theirs. In the case of standard input(10-11A/cm2), the gain of MCP is high, the uniformity of gain is improved, the fixedpattern noise is in the level of 0～1, the definition of FOV is high.
