Neutron Depth Profiling (NDP) is a nuclear analytical method based on determining the energy loss of charged particles in matter. This loss depends on the thicknesses and the densities of the layers between the place of emission and the detector. The new set-up at the PGAA facility enables a non-destructive quantitative analysis based on the maximum energies of the spectral shapes, as well as a reconstruction of the depth profiles based on the energy losses.

The method is very sensitive to certain light elements/ nuclides (³He, ⁶Li, ¹⁰B or ¹⁴N) with detection limits down to the ppb range. The depth resolution can be as good as 5 nm, but it is highly matrix-dependent. One of the most important applications of NDP is battery research (lithium-ion-batteries). An NDP measurement is also possible in operando during the charge cycles of batteries.

• Non-destructive depth profiling
• Detection of the following stable nuclides: ³He, ⁶Li, ¹⁰B, ¹⁴N, ¹⁷O, ³³S, ³⁵Cl
• Detection of radionuclides: ⁷Be, ²²Na, ³⁷Ar, ⁴⁰K, ⁵⁹Ni, ²¹⁰Po
• Depth profiling is possible in almost any material matrix
• Depths <50 µm accessible (material-dependent)
• Max. depth resolutions 5 nm possible (material-dependent)
