Light Output Analysis of 3D Printed Plastic Scintillator

3D printing technique based on additive manufacturing can facilitate to manufacture plastic scintillators in innovatively fast time (10 minutes to 4 hours). For a practical use in radiation detection systems, 3D printed plastic scintillator has been studied to improve scintillation light output. In the previous study, it was confirmed that the amounts of 1-methyl-naphthlane in the composition of plastic scintillator improves light output of the scintillator. The measured data were compared to that of BC408 commercial plastic scintillator (Saint-Gobain Crystal). Light output and transmission of the 3D printed plastic scintillators with the different amounts of 1-methyl-naphthalene were measured and analyzed. The measured light output and transmission was improved with the amounts of 1-methyl-naphthalene, but the saturation of light output began above 1-methyl-naphthalene 60%. Given the above fact, it is expected that the additional effect factors on light output other than transmission should be considered such as the number of benzene rings in the composition of the scintillator and oxygen quenching effect.
