Abstract
Development and testing of a dual microchannel plate (MCP) module to be used in the national inertial confinement fusion (ICF) program has recently been completed. The MCP module is a key component of a new monochromatic x-ray imaging diagnostic which is designed around a four channel Kirkpatrick–Baez microscope and diffraction crystals and is located at the University of Rochester’s Omega laser system. The MCP module has two separate MCP regions with centers spaced 53 mm apart. Each region contains a 25 mm MCP proximity focused to a P-11 phosphor coated fiberoptic faceplate. The two L/D=40, MCPs have a 10.2 mm wide, 8 ohm stripline constructed of 500 nm copper overcoated with 100 nm gold. A 4 kV, 150 ps electrical pulse provides an optical gatewidth of 80 ps and spatial resolution has been measured at 20 lp/mm.
