Three-strip microchannel plate gated x-ray framing camera

Abstract

Abstract A microchannel plate (MCP) gated x-ray framing camera with three-strip is reported. The diameter of the MCP is 56\u2009mm and the width of each microstrip line cathode deposited on the MCP is 8\u2009mm. While the microstrip line cathode is driven by a gating electrical pulse with width of 200\u2009ps and amplitude of −1.9\u2009kV overlapped with a −200\u2009V DC bias, the measured temporal resolution is about 68\u2009ps. Furthermore, the gain uniformity of the microstrip line cathode is measured showing that there is a 3.6× drop in gain along the pulse propagation direction, whereas the variations in the gain transverse to the pulse propagation direction are within 10%.
