DESCRIPTION:Speakers: Tikhon Kozin ()\nThe work reports result of studies 
 conducted to improve scintillation performance of plastic scintillators (P
 S) capable of neutron/gamma pulse-shape discrimination. A research group l
 ed by Zaitseva from LLNL made a major contribution to the field of develop
 ment such materials. However\, despite the accumulated experience of mater
 ial production\, there is a demand to modify their composition in order to
  improve their optical\, scintillation and mechanical characteristics. Com
 mercial products with good scintillation properties (EJ276D) are currently
  difficult to purchase. In this regard\, the creation of domestic\, commer
 cially available analogues is relevant for solving problems in fundamental
  and applied physics.\nIn this work\, methods for obtaining plastic scinti
 llators with PSD capability were reproduced. Poly(styrene-co-divinylbenzen
 e) was used as the scintillation base and 2\,5-diphenyloxazole\, para-terp
 henyl\, a mixture of diisopropylnaphthalene isomers and diphenyl were used
  as fluors. The light yield\, transparency\, figure of merit and hardness 
 of the obtained PS samples were measured. The best performance for a sampl
 e with the composition 40% PPO\, 0.2% POPOP\, 7.5% DVB was achieved. The l
 ight yield was 1.12±0.05\, the transmittance coefficient (optical path le
 ngth 1 cm) at a wavelength of 430 nm was 0.72±0.02\, the figure of merit 
 for n/γ pulse shape discrimination was 3.65±0.13\, and the Shore D hardn
 ess was 48±2. The obtained results are compared with the EJ276D sample an
 d literature data.\n\nhttps://indico.particle.mephi.ru/event/626/contribut
