Quantitative trace hydrogen distributions in natural diamond using 3D-micro-ERDA microscopy

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998
Abstract A 3-D quantitative microscopy for minor distributions of surface and near-surface bulk hydrogen in solid samples has been developed. The technique employs a 15 MeV Si 7+ microbeam and a two-dimensional position sensitive detector (2D PSD) with event reconstruction in an Elastic Recoil Detection Analysis (ERDA) geometry.

Quantitative microstructure characteristics of landslide soil affected by Three Gorges Reservoir with using ERDAS

The 2nd International Conference on Information Science and Engineering, 2010
The study on soil microstructure has transferred from qualitative description to quantitative analysis as the improvement of image processing technology. However, it is difficult that how to apply the quantitative technology to solve practical problems. We used ERDAS to quantify microstructure images of landslide soil in the Three Gorges Reservoir area,

Complementary use of ERDA and RBS/C for the determination of implanted atom and damage distributions in spinel

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
Abstract Crystalline oxide ceramics (particularly, zirconia and spinel) are promising matrices for nuclear waste immobilization and/or transmutation. The behavior of implanted ions and of radiation damage is a very important issue in the qualification of nuclear matrices. Ion beams provide very efficient tools for such an evaluation.

Simultaneous multielement ERDA using a simple detector system and extremely heavy ion beams

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996
Abstract The use of very heavy ion beams such as Au or Bi in elastic recoil detection analysis (ERDA) is increasing rapidly. However, one of the experimental problems is the simultaneous detection of the full range of recoil atoms ejected by such extremely heavy ion beams, since all low-mass surface recoils have almost identical velocity and also ...

Determination of hydrogen content in geological samples using elastic recoil detection analysis (ERDA)

Geochimica et Cosmochimica Acta, 2009
Abstract The present study illustrates the interest of using the elastic recoil detection analysis (ERDA) method to characterize any geological sample matrix with respect to hydrogen. ERDA is combined with Rutherford back scattering (RBS) and particle induced X-ray emission (PIXE), allowing the simultaneous characterization of the matrix with respect

Analysis of hydrogen in corrosion product films on molybdenum and niobium using ERDA technique

International Journal of Hydrogen Energy, 1999
Elastic Recoil Detection Analysis (ERDA) technique with 1H(α,α)1H forward scattering was used at 3.0 MeV to analyze hydrogen in corrosion product films formed on molybdenum and niobium surfaces at selected potentials of the anodic and cathodic potentiodynamic scan.

Stopping power of carbon for Si, Fe, Ni and Cu ions using the ERDA technique

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997
Abstract We have been carrying out systematic random stopping power experiments in the low velocity region ( ν 0 to 5 ν 0 , where ν 0 is the Bohr velocity) using heavy ions ( Z 1 = 8 to 29). The objective is to supplement in a significant way the currently available scanty data in this region.

Quantitative analysis of hydrogen in thin films using TOF ERDA spectroscopy

Thin solid films, 2010
Determination of atomic concentrations in thin films is one of key problems in materials science. Time-of-Flight Elastic Recoil Detection Analysis (TOF ERDA) is a powerful method for depth profiling of light and medium mass elements in near surface layers of material.
