The installation of a vertical single ended 5.5 MV Van de Graaff accelerator has been completed and it has been operational since 1989. The different types of ion beam (p, d, He-3, He-4, N-14, N-15, etc.) with energies above 1 MeV obtained with this accelerator have turned it into a very versatile tool for analyzing solids. Most of the IBA techniques are available: backscattering, (p, alpha) and (p, gamma) nuclear reaction resonances, (d, alpha) and (d, p) reactions, PIXE, etc. A brief summary of the measurements is presented.
