Research progress on neutron depth profiling at China advanced research reactor
摘要
A neutron depth profiling (NDP) system was established at a cold neutron beam of China Advanced Research Reactor (CARR). In the recent years, we have upgraded the CARR NDP facility and made considerable advancements in spectral deconvolution methodology and related experiments. In 2023 CARR has been operational for over 100 days, conducting various experiments utilizing the NDP apparatus. These experiments encompassed several objectives: measurement thin films thickness, Li transportation and distribution in cathode materials and B distribution in semiconductor materials.
