Abstract
To create a prototype of a detector based on a neodymium-containing liquid organic scintillator for the search for neutrinoless double-beta decay of \({}^{150}\) Nd, measurements of the spectra of radioactive impurities from various materials used in the manufacture of the detector were carried out using low-background semiconductor gamma spectrometers at the Baksan Neutrino Observatory, Institute of Nuclear Research of the Russian Academy of Sciences. The potential use of 3D printing in low-background conditions was considered. This could potentially allow creating the detector structural elements with a record-low content of radioactive impurities for experiments in neutrino astrophysics, dark matter searches, neutrinoless double-beta decay experiments. The activity of radioactive impurities in plastic parts produced on a 3D printer, which were intended for use in creating a prototype of a detector and its low-background shielding, were measured.
