We present ion beam erosion experiments performed in ultrahigh vacuum using a differentially pumped ion source and taking care that the ion beam hits the Si(001) sample only. Under these conditions no ion beam patterns form on Si for angles theta < or = 45 degrees with respect to the global surface normal using 2 keV Kr+ and fluences of approximately 2 x 10(22) ions m(-2). In fact, the ion beam...
The MedAustron Ion therapy center will be constructed in Wiener Neustadt (Austria) in the vicinity of Vienna. Its accelerator complex consists of four ion sources, a linear accelerator, a synchrotron and a beam delivery system to the three medical treatment rooms and to the research irradiation room. The ion sources shall deliver beams of H3, C and light ions with utmost reliability and stabili...
To meet the increasing needs of modern heavy ion accelerators, ECR ion source must be developed to deliver high intensity high brightness high charge state ion beams, in terms of accelerator output power and beam transmission efficiency. With the success in several laboratories on fully superconducting ECR ion source development, the performance of highly charged heavy ion beams have been great...
A 60 keV neutral Lithium beam system was designed and built up for beam emission spectroscopy measurement of edge plasma on KSTAR. The measurement will be the complementary of the heating beam based emission spectroscopy system which was built up in 2012, using the same observation system with different interference filters. The electron density and its fluctuation, thus the density distributio...
Formation of keV-energy Ar cluster ion beam is studied. Optimum condition for formation high intensity cluster beam with 2*10 16 clusters/sm 2 *sec investigated both experimentally and by numerical simulation. The mass distributions of the accelerated cluster ion beam were measured. It has been demonstrated that mass spectrum of cluster ion depend of collision processes between the ions during ...
