Heavy ion-induced desorption investigations using UHV-ERDA

Vacuum, 2007
Abstract Ion–beam-loss induced desorption is a well known intensity limitation for high current, low charge state heavy ion accelerators like the heavy ion synchrotron SIS18 at GSI. Therefore dedicated measurements of desorption yields has been made, e.g., at CERN and at GSI in the last few years. In this work we will present studies performed at GSI

Hydrogen mobility in diamond studies using HI-ERDA microscopy

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997
Abstract Hydrogen plays a significant role in the growth of diamond and in the determination of its physical, electrical and optical properties. However, despite this significance, the configuration, chemistry and behaviour of hydrogen in the diamond lattice is still not very well understood.

Depth resolution of TOF-ERDA using a He beam

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2011
Abstract Depth resolution of time-of-flight ERDA using a 4He beam (He TOF-ERDA) has been studied. The measurement system consists of a time detector of the ion transmission type and a silicon surface-barrier detector. Depth resolution was measured using samples of carbon layers on silicon wafers and 4He beams with energies between 3.5 and 10.1 MeV ...

Light element analysis using ERDA method with an ionization chamber

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
Abstract An elastic recoil detection analysis (ERDA) system using ΔE−E technique was assembled for stoichiometric and depth profile studies of materials formed by light elements. An ionization chamber with a surface barrier detector (SBD) was used in this work.

Hydrogen microdetermination in geological materials using elastic recoil detection analysis (ERDA)

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1990
Abstract For the first time, hydrogen has been determined (by means of nuclear microanalysis) within glassy inclusions trapped in volcanic minerals. Elastic recoil detection of protons has been used by means of the transmission and reflection geometry.

Anodic behavior of zinc in Zn-MnO2 battery using ERDA technique

International Journal of Hydrogen Energy, 2010
The commercial, alkaline zinc-manganese dioxide (Zn-MnO2) primary battery has been transformed into a secondary battery using lithium hydroxide electrolyte. Galvanostatic discharge-charge experiments showed that the capacity decline of the Zn-MnO2 battery is not caused by the MnO2 cathode, but by the zinc anode.

ERDA of hydrogen and helium using an 8 MeV 16O beam

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1990
Abstract An 8 MeV 16O beam was used to profile the depth concentration of 1,2H and 4He implanted into silicon wafers and stainless steel (SUS316). The measured energy spectra of recoiled particles have been unfolded to obtain depth profiles. The TRIM'86 data have been utilized to calculate the response matrix which takes account of the energy loss of

Measurement of very low bulk concentrations (below 1 ppm) of hydrogen using ERDA

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004
The measurement of small quantities of hydrogen (a few ppm) present in the bulk of materials by elastic recoil detection analysis is very difficult as the sensitivity is limited by a high background, almost continuous in level, in the low energy region, i.e. bulk region of the spectrum.

Behavior of Li on graphene surfaces observed using high-resolution ERDA

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2016
Abstract Behavior of Li atoms deposited on the surfaces of highly oriented pyrolytic graphite (HOPG) and graphene-based thin films were observed at room temperature using high-resolution elastic recoil detection analysis (ERDA). On the HOPG surface, the deposited Li atoms intercalate into the bulk and no Li was observed in the surface region.

Trace elementary concentration in enamel after dental bleaching using HI-ERDA

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006
Abstract Changes of elementary concentrations in dental enamel after a bleaching treatment with different products, is presented, with special focus on the oxygen contribution. Concentrations for Ca, P, O and C and some other trace elements were obtained for enamel of bovine incisor teeth by HI-ERDA measurements using a 35 Cl incident beam and an ...
