英文摘要	Micro Pattern Gaseous Detector (MPGD) is a promising and competitive technology for thermal neutron imaging, due to its many advantages such as high counting rate, low mass, irradiation resistance, and excellent position resolution. In order to further improve spatial resolution, a vertex reconstruction of neutron conversion tracks can be employed. Moreover, the accompanying gamma-ray background also has a significant impact on the detector performance. In this work, a detector for thermal neutron detection was developed based on GEMs, with a B4C-coated Mylar foil as the converter. Track reconstruction and vertex correction were achieved with additional use of the information of each signal. The rising time and energy were utilized to improve the track reconstruction furthermore. Finally, the spatial resolution was improved to 0.23mm from 1.01mm significantly for thermal neutron detection.
