6Li-loaded liquid scintillators produced by direct dissolution of compounds in diisopropylnaphthalene (DIPN)

The paper describes preparation of $^6$Li-loaded liquid scintillators by methods involving direct dissolution $^6$Li salts in the commercial diisopropylnaphthalene (DIPN) solvent, without formation water-in-oil emulsions. Methods include incorporation that, unlike previously reported formulations, does not require additions water or a strong acid such as hydrochloric (HCl). Results conducted experiments show that aromatic and aliphatic DIPN can be easily achieved at 0.1- 0.3% weight atomic $^6$Li, using small waterless surfactants, mild carboxylic acids. An alternative way suggests part surfactant molecule dissolved any solubilizing additions. Proposed enable efficient large scale 50 cm, exhibit good pulse shape discrimination (PSD) properties combined with up to 107% light output 115% attenuation length measured relative standard undoped EJ-309 scintillator.
