dc.description.abstractA heavy ion elastic recoil time of flight (ERTOF) spectrometer has been built on the ion beam analysis (1BA) beam line of the 8 MV tandem particle accelerator at the Australian Nuclear Science and Technology Organisation (ANSTO). The spectrometer consists of two electrostatic mirror time detectors, as described in the literature by Whitlow et. al. and Busch et al. at the forward scattering angle of 45°, and an ion-implanted surface barrier energy detector. The flight length of 750mm gives a typical timing resolution of a few hundred pico-seconds. The use of high energy heavy ions in recoil spectrometry is ideally suited to the analysis of light ions in heavy matrices, though the analysis of recoil spectra presents some ambiguity due to the overlap of individual depth profiles. An HRTOF spectrometer, with incident 77MeV 127 I 10+ as designed here, allows individual depth profiling of most elements contained within the matrix, even those in close proximity in the periodic table, therefore providing an unambiguous profile and greater certainty in sample analysis. This paper will outline the design and principles of the ERTOF spectrometer built on the IBA beam line at ANSTO. The application of this technique to materials analysis and such examples as YBCO superconductors and AlGaAs semiconductors systems will also be presented.en_AU
