The objective of the proposed study is to use ANSTO’s transmission electron microscopy (TEM) and elastic recoil detection analysis (ERDA) combined with Rutherford back scattering (RBS). TEM and its associated techniques like HR-TEM (High resolution) and electron energy loss spectroscopy (EELS) are proposed to determine the lattice fringes and electron diffraction pattern with d-spacing correspo...

Nuclear microprobe at 2 MV Tandetron accelerator of Jozef Stefan Institute (JSI) was constructed in the year 2000 with the support of IAEA Technical Cooperation Project SLO/1/004. The measuring station is equipped with instrumentation for micro-Proton-Induced-X-ray-Emission (micro-PIXE), micro-Elastic Recoil Detection Analysis (micro-ERDA), micro-Nuclear Reaction Analysis (micro-NRA), Proton Be...

Due to the unique characteristic of Mobile Ad hoc Network (MANET) and lack of security in its routing protocol, MANET is vulnerable to various attacks such as Black hole. In this paper we study a Black hole attack on one of ad hoc routing protocol called AODV (Ad hoc On Demand Vector). There have been many works done to solve this problem but most of them introduced extra overheads. In this pap...

Depth resolution and probing depth for Li in lithium thin film batteries achievable using different ion beam analytical techniques were investigated. Experiments protons nuclear reaction analysis, He ions time-of-flight (TOF) energy elastic recoil detection analysis (ERDA) transmission geometry, as well coincidence ERDA geometry are performed. Experimental results compared terms of the obtained...

Ion-induced desorption is a serious luminosity limitation for high current and low charge state heavy ion accelerators [1]. In order to find low desorbing materials for the loss regions of SIS18 a dedicated experimental program was started measuring desorption yields of different materials, which are in-situ well characterized using UHV Elastic Recoil Detection Analysis (ERDA). Two targets, wit...

In heavy ion accelerators the beam line vacuum is effected by lost ions impinging on the beam pipe. Due to ion induced desorption gas is released from the walls into the vacuum. This vacuum degeneration effects the ion beam life time and is a serious luminosity limitation for a heavy ion synchrotron like SIS18. Here we report on a new approach to understand the physics of the ion induced desorp...
