Abstract: High-rate Neutron Depth Profiling (NDP) is a very efficient and precise probe for studying the evolution of lithium concentration in thin-layer structures, e.g., battery electrodes. NDP is typically limited to a one-dimensional depth analysis summed over the profile area covered by the neutron beam. We developed a detector system based on double-sided silicon strip detectors (DSSSD) with extremely thin and homogeneous entrance windows to provide a new quality of NDP measurements in dimensions for the N4DP instrument at the FRM II in Garching, Germany. Using the 6Li(n, a)3H reaction in an experiment conducted at the research reactor in Delft, we achieved a lateral position resolution down to 100 um and an energy resolution with 10 keV for the triton particles at energies of 2.7 MeV. High-resolution 3D pictures with a contrast uncertainty per pixel can be achieved faster than 1 picture per minute. This rate can be adjusted individually for each experiment by sacrificing granularity in the position measurement.
