Abstract:
Coincident elastic proton-proton scattering at a 17 MeV microprobe is used to investigate hydrogen distributions on microscopic scale inside freestanding samples up to some 100 μm thickness. Hydrogen imaging at atomic ppm level needs a total count rate of about 100 kHz of scattered protons in order to get sufficient statistics from the small fraction of coincident hydrogen signals. It is obtained using a highly segmented silicon strip detector of 2.3 sr for proton currents of less than 100 pA im...    »
