Abstract :
Thermal neutron imaging with Eu doped 6LiCaAlF6, which is a novel thermal neutron scintillator, was demonstrated. Eu doped 6LiCaAlF6 single crystal was grown by Czochralski technique and grown crystal was cut and polished to a plate shape. Setup of the thermal neutron imaging consisted of the plate shaped Eu doped 6LiCaAlF6, a position sensitive photomultiplier tube, Cd-mask and 252Cf in the polyethylene container. As a result, clear neutron image was successfully observed.
