Research of low-background neutron scattering furnace and perforated heating element at CSNS
Metal foil element furnaces are widely used in neutron scattering sample environments. However, since the metal foil blocks the neutron beam, these furnaces typically have a large background from the metal foil. Therefore, we designed a special heating element with an innovative perforated structure for the furnace. This novel heating element can significantly reduce the instrumental background, and is specifically applicable to the Multi-Physics Instrument and High-Pressure Neutron Diffractometer in CSNS. This structure reduces material obstruction of the neutron beam, thereby greatly lowering the experimental background. Additionally, we performed electro-thermal-mechanical coupled finite element simulation on the heating element to analyze its temperature and stress distribution, and identified the locations most susceptible to failure. We adjusted the heating element's hole size to study temperature and stress changes, providing a theoretical basis for future optimization of the heating element. This furnace is extensively applied in CSNS, facilitating users in accomplishing neutron scattering experiments and achieving a series of research outcomes.
