Light output uniformity of czochralski grown rare-earth-ion doped 6LiCaAlF6 single crystal for thermal neutron detection

Light output uniformity of Ce doped <sup>6</sup>LiCaAlF<inf>6</inf> single crystal was researched. Ce doped <sup>6</sup>LiCaAlF<inf>6</inf> single crystal was grown by Czochralski technique and several parts of the crystal were cut from grown crystal and polished. Position dependence of radioluminescence spectra and pulse height spectra were investigated.
