Study of the Possibility of Using 3D Printing in Low-Background Experiments

The paper considers the possibility of using 3D printing technology to manufacture structural elements of ionizing radiation detectors. For this purpose, a housing for a scintillation detector with a volume of approximately 73 cm $${}^{3}$$ was printed. Based on this printed housing, a scintillation detector was constructed, utilizing a scintillator made from LAB with additives of PPO (2 g/L) and Bis-MSB (0.02 g/L). The volume of the detector was viewed using a PMT-97. To verify the functionality of the experimental setup, calibration measurements were conducted with a $${}^{137}$$ Cs source, and a background spectrum was collected over 16 hours in the laboratory building of the BNO INR RAS. The results obtained confirmed the feasibility of using 3D printing for the fabrication of structural components of detectors.
