He Ions for 3D Imaging
A theoretical model of He ion imaging for acquisition of a stack of image slices with applications in 3D tomography previously showed that ion implantation accumulates with each image scan [1]. The accumulated ion implantation can result in damage to the target depending on image dose per slice and slice thickness. The imaging ion energy and incidence angle will also influence the accumulated i...
متن کاملDirect excitations of He+ and Li++ ions by collisions with protons or antiprotons
The impact parameter formalism of the single-center close-coupling, first-, and second-order Born approximations have been applied to investigate direct excitations of Helium He+(2s) and Lithium Li++(2s) ions by colliding with protons or antiprotons. The total 3s, 3p, and 3d scaled excitation cross sections are calculated in the scaled impact energy region (2 to 1000 keV). The present work aims...
متن کاملMaxwell-Boltzmann Distribution for He Ions
Statistical mechanics deals with systems having a large number of particles. In statistical mechanics, large scale properties (such as temperature, pressure etc) are studied by applying probability theory to a large number of small particles. Hence this is a probabilistic theory and the behaviour of all of the system is studied using the average individual behaviour of particles. With small num...
متن کاملCOLTRIMS Imaging of Molecular Fragmentation Dynamics of CO Molecules Induced by Slow He Ions
We study the multiple ionization and fragmentation of CO in collisions with slow He ions. Correlated measurements of all fragment ions and the projectile final charge state were performed using our coincidence COLTRIMS imaging technique coupled to projectile charge state separation. Complete fragmentations of CO, following double electron capture, into C+O with a total charge of 4 were investig...
متن کاملDesign and Manipulation 3D Imaging System by using Photodiode Grid
Introduction: Radiation imaging is one of the applicable methods in diagnostic medicine and nondestructive testing for industrial applications. In nondestructive 3D imaging, in addition to the radiation source, there is a requirement for a suitable detection system, data acquisition system, mechanical sections for moving objects, reconstruction algorithm and finally a computer for processing an...
