Elastic recoil detection analysis (ERDA) with heavy ion beams has evolved into a universal ion beam analysis (IBA) method for simultaneous analysis of almost all elements, with an essentially constant detection sensitivity. It is therefore interesting to compare the values for Ks and IC, at various detection angles as a function of the considered mass ratio. One non-destructive technique for performing these measurements would be elastic recoil detection (ERD), if a detection scheme can be devised to separate detected 3 He from tritium while allowing measurement of other elements of interest, such as O. These exemplified the main characteristics of elastic recoil detection analysis (ERDA): its sensitivity to depth distribution and its ability to detect light elements in heavy substrates. In this way, ERDA data are collected for each raster point on the surface. PRINCIPLE OF … In this way, ERDA data are collected for each raster point on the surface. and you may need to create a new Wiley Online Library account. The ceramic is very leach resistant in aqueous media, but this leach resistance makes it very difficult to study the detailed mechanisms of aqueous dissolution. So, we are finished now with RBS. NRA technique at ANSTO has also been applied in a variety of other studies, such as the manufacture of amorphous hydrogenated silicon solar cells, and segregation in deuterated block copolymers. In this technique, an incident ion beam is directed at a grazing angle onto the sample's surface. The energy of the recoiling atoms is analyzed by a surface barrier detector to create a spectrum of the recoil atoms as shown in Fig. That is the recoil particle, the M2. With these very low leach rates, the ambient hydrogenous background can easily mask out surface alteration effects. Unlimited viewing of the article/chapter PDF and any associated supplements and figures. We have called the method Micro-scanned Elastic Recoil Detection Analysis (mERDA).

In ERDA, different elemental spectra superimpose on each other, and it is, therefore, difficult to sort these separate masses so as to provide unambiguous data on the different elemental depth profiles. ANSTO Synroc is a titanate ceramic designed for the immobilisation of high-level radioactive waste from reprocessing of spent nuclear fuel. The entry of Synroc ions into aqueous media, however, is not the only process taking place during dissolution. These exemplified the main characteristics of elastic recoil detection analysis (ERDA): its sensitivity to depth distribution and its ability to detect light elements in heavy substrates. Studies of the hydrogen content and profiles of surfaces can be difficult in some cases, due to the pickup of atmospheric moisture by the sample causing an unwanted hydrogenous background. The large hydrogen surface peak was not much affected after the drying, but atmospheric recontamination could not be avoided. ... Elastic Recoil Detection Analysis (ERDA) Elastic Recoil Detection (ERD) Particle Recoil Detection (PRD) Extended X-Ray Absorption Fine Structure (EXAFS) The ready availability of low energy helium beams from small accelerators quickly made ERDA a popular technique for the determination of hydrogen in solids, and studies of polymer interdiffusion. However, the use of heavy water (D2O) rather than normal water H2O for leaching Synroc provides an unambiguous signal in ERDA measurements. In this technique, an incident ion beam is directed at a grazing angle onto the sample's surface. The difference in deuterium content after drying at lower temperatures presumably reflects weakly sorbed D, while that surviving at the higher temperatures probably represents deutroxylated species. This technique employs a high energy heavy ion beam to eject nuclei from the target and uses a time of flight and energy dispersive (ToF-E) detector telescope to detect these nuclei. By means of Monte Carlo (MC) simulations, the interpretation and reliability of the results have increased greatly over the last few years. A thin filter, typically mylar, is placed in front of the detector to stop and block-out the elastically scattered incident ion beam, which would otherwise overload and quickly destroy the detector.
