Abstract
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%

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%

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.
