摘要：I show possibility of directional measurement of electron anti-neutrinoswith liquid scintillator
detector. Relative vertex position of prompt positron and delayed neutron events is useful to
extract directional information of anti-neutrinos. In orderto minimize diffusion of thermal
neutron and capture signal, development of new liquid scintillator containing an isotope which
goes to (n,α) interaction with large cross sectionis needed. Also, development of an imaging
device to obtain high vertex resolution is necessary. The key issue in the development is the
optics with large depth of field and appropriate aperture. In addition, the photo-sensor should
have one-photo-electron sensitivity and position information.
