Thallium bromide (TlBr) is a semiconductor attractive for gamma-ray detectors and imagers. In order to realize a large size TlBr detectors, we should discuss crystal quality. As the crystal quality evaluation methods, we applied neutron Bragg-dip imaging, which is based on the neutron diffraction technique.
