Progress report on Aramis, the 2 MV tandem at Orsay

Formation and evolution of lateritic profiles in the middle Amazon basin: Insights from radiation-induced defects in kaolinite

“…Alpha-particle effects were simulated with He ϩ ions beams of 1.5 MeV and 20 -30 nA current density, at the ARAMIS electrostatic accelerator (Orsay, France;Bernas et al, 1992). Five He ϩ ion fluences were used within 5 10 11 -10 13 ions/cm 2 , corresponding to a dose range of 127-2545 kGy.…”

Reduced magnetic moment per atom in small Ni and Co clusters embedded in AlN

“…24 The He incident energy has been chosen in order to record Ni or Co peaks well separated from the AlN signal. The Co and Ni peak area were compared to the Bi one, a standard sample measured in similar conditions, in order to deduce the number of Ni or Co ions in the targets with an uncertainty of 0.05ϫ10 17 at/cm 2 .…”

Characterization of bond formation in SiC and Si3N4 implanted with Ti, Fe, and Co

“…11 On all asimplanted samples and on some selected annealed samples, Rutherford backscattering experiments with He particles of 1.5 MeV were performed to check the implanted profile and amount of remaining ions in the target. 21 Analysis of the RBS spectra was done using the RUMP code. 22 Projected ranges, implanted profile widths, number of remaining ions in the targets, and corresponding concentrations are reported in Table I. B. X-ray absorption spectroscopy X-ray absorption spectroscopy (XAS) was performed on the D42 station of the DCI ring of LURE running at 1.85 GeV and 300 mA.…”
