Improved (10)B-loaded liquid scintillator with pulse-shape discrimination.
An improved (10)B-loaded liquid scintillator solution has been developed containing trimethylborate, 1-methylnaphthalene, and 9,10-diphenylanthracene. Cells up to 5 cm in diameter by 15.2 cm long have been prepared and tested with (10)B-loadings up to 7.2% by weight (80% trimethylborate). The solution has excellent light output and pulse-shape discrimination properties and is stable at temperatures as low as -17 degrees C. Neutron efficiency calculations are also presented.
