The applications of neutron radiograph were introduced.As adding directly neutron-absorbing atoms into Micro-channel Plate(MCP) glass would make the MCP sensitive to neutrons,and the advantages of a MCP event counting imaging detector would be successfully extended to the imaging detection technologies,this paper explores the thermal neutron sensitive MCPs.By adding directly 3 mol% natGd2O3 into MCP glass composition and using a conventional fabrication process,the large format neutron-sensitive MCPs with diameters of 50 mm and 106 mm were fabricated and the high efficiency event-counting thermal neutron imaging experiments were completed by using this Gd doped neutron-sensitive MCPs.The theory and experiments verify that this 3 mol% natGd2O3 doped neutron-sensitive MCP realizes the detection efficiency of 30%—50% for thermal imaging or cold neutrons.This work now is further proceeding to develop a sealed neutron sensitive MCP intensified tube,because the compact neutron camera based on a hybrid sensor configure via optical couple to a CCD or a CMOS camera is a promising approach to high temporal and spatial resolution neutron radiographic nondestructive test technology.
