Fast-Response and Low-Afterglow Cerium-Doped Lithium 6 Fluoro-Oxide Glass Scintillator for Laser Fusion-Originated Down-Scattered Neutron Detection

Scintillation properties of Ce
$^{3+}$
-doped 20Al(PO

$_{3}$
- 80LiF glasses were investigated in order to seek a candidate for down-scattered neutron scintillator in nuclear fusion diagnostics. The decay constant of
${\hbox {APLF80}} + 3$
Ce with 5.5 MeV alpha particles from
${}^{241}$
Am radioisotope excitation was measured to be 32.1 ns. Moreover, sufficiently low afterglow decay profile and improved light output of
${\hbox {APLF80}} + 3$
Ce were experimentally demonstrated.
