Patent number: 10266761Abstract: In one embodiment, a scintillator material includes a polymer matrix; and a primary dye in the polymer matrix, the primary dye being a fluorescent dye, the primary dye being present in an amount of 5 wt % or more; wherein the scintillator material exhibits an optical response signature for neutrons that is different than an optical response signature for gamma rays. In another embodiment, a scintillator material includes a polymer matrix comprising at least one of: polyvinyl xylene (PVX); polyvinyl diphenyl; and polyvinyl tetrahydronaphthalene; and a primary dye in the polymer matrix, the primary dye being a fluorescent dye, the primary dye being present in an amount greater than 10 wt %. A total loading of dye in the scintillator material is sufficient to cause the scintillator material to exhibit a pulse-shape discrimination (PSD) figure of merit (FOM) of about at least 2.0.Type: GrantFiled: March 7, 2016Date of Patent: April 23, 2019Assignee: Lawrence Livermore National Security, LLCInventors: Natalia P. Zaitseva, M Leslie Carman, Nerine Cherepy, Andrew M. Glenn, Sebastien Hamel, Stephen A. Payne, Benjamin L. Rupert
