We have performed mechanical finishing operations on Sverker 21 (traditional) and Vanadis 6 (advanced powder) steel surfaces: grinding, turning, and turning followed by slide burnishing. Then each specimen was subjected in turn to focused ion beams o

The freely available “Stopping and Range of Ions in Matter” (SRIM) code is used for evaluating ion beam ranges and depth profiles. We present secondary ion mass spectrometry and Rutherford backscattering experimental results of Si samples implant

Dilute alloys of bismuth in gallium (98-99% at.) are known from theoretical calculations and x-ray scattering to display a strong segregation of bismuth atoms at the surface, a monatomic layer of bismuth appearing because of the lower surface tension

ZnO and Zn 2 SiO 4 nanoparticles have been synthesized by dual beam implantation of 45 keV ZnO − molecular ions and 15 keV O − ions into Si (100) substrates at room temperature to fluences of 1 × 10 17 and 2 × 10 17 ions/cm 2 , respectively. Im

The dependences of the total sputtering yield of Bi and the differential angular distribution of these sputtered Bi atoms on the fluence of 50 keV Ar + ions at normal incidence have been experimentally measured. Polycrystalline Bi targets were used f

A plasma enclosed by an Artificially Structured Boundary (ASB) is proposed here as an alternative to existing ion source assemblies. In accelerator applications, many ion sources can have a limited lifetime or frequent service intervals due to sputte

The authors investigate the mechanism for etching of exfoliated graphene multilayers on SiO2 by low-energy (50 eV) electron irradiation using He plasma systems for electron sources. A mechanism for this etching has been previously proposed in which t

Pneumatic energy is converted into solid particle kinetic energy as a solid-particle-entrained gas flows downward through a vertical nozzle. For the conditions studied, the solid particles serve as a heat exchange medium to enable a gas expansion tha
