Abstract: An event-counting thermal neutron imaging detector based on 3 mol % natGd2O3 doped micro channel plate (MCP) has been developed and tested. Thermal neutron imaging experiment was carried out with a low flux neutron beam. Detection efficiency of 33 % was achieved with only one doped MCP. The spatial resolution of 72 {\mu}m RMS is currently limited by the readout anode. A detector with larger area and improved readout method is now being developed.<br />Comment: 4 pages, 4 figures
