TARGISOL project optimization of the release properties of ISOL targets NPI Rez - Thermal Neutron Depth Profiling (TNDP). study of diffusion of some light elements in selected ISOL targets Diffusion coefficient D can be deduced from the broadening of the TNDP profiles D = D 0 e-e/k. T D 0 – pre-exponential constant e – activation energy k – Boltzman constant T – temperature (in 0 K) Example of the TNDP analysis: 350 ke. V 10 B implanted into Ba. F 2 annealed 60 min at 4170 C. The analysis of the broadening of the boron profiles gives the diffusion coefficient D = 2 x 10 -13 cm 2. s THERMAL NEUTRON DEPTH PROFILING
