Proton induced damage in LFS-3 and LFS-8 scintillating crystals
  Scintillating LFS-3 and LFS-8 crystals were exposed to a 155 MeV/c proton fluence $\Phi_{p}=(4.4\pm0.4)\cdot10^{12}cm^{-2}$. There was negligible reduction in transmission spectrum of LFS-3 crystal measured in 30 days after irradiation.
