We are developing a neutron beam monitor with a gas electron multiplier (GEM) for the high-intensity total diffractometer at J-PARC. We checked the validity of the wavelength-spectrum distribution and the two dimensional image. The GEM-based detector operated well in the neutron irradiation test carried out at J-PARC. Therefore we found that as a neutron beam monitor, the GEM-based detector has good two-dimensional imaging ability.
