B70 Materials Research Laboratory

General
The Van de Graaff operates at energies up to 2.3 MeV for H, He, Ar, Kr , Xe and Ne with 1-2-3 mm beam-size apertures. There is a beam line for Rutherford backscattering spectroscopy (RBS), elastic recoil detection. Nondestructive depth profiles of thin films can be obtained as deeply as several microns into the sample. Available source gases include H, He, Ne, Ar, and Kr. The sample goniometer can be set to allow or prevent channeling.
