In high energy physics, an imaging detector which consists of multi anode PMT (MAPMT) and pixel scintillators having a size of several mm square is used. In this kind of detector, a spatial resolution is limited by a size of scintillator pixel, because scintillator arrays which have size of sub-mm square are difficult to be made. Today, our group successfully developed single crystal growth technology of BGO fiber with a 100 μm and 100 mm length by using the micro-pullingdown method. When coupled with APD and irradiated by gamma-ray radio isotopes of 22Na and 137Cs, 511 keV and 662 keV photo-absorption peaks are clearly obtained, respectively.
