Recent years have seen a great potential of the focused ion beam (FIB) technology for the nanometer-scale patterning of a freestanding two-dimensional (2D) layer. Experimentally determined sputtering yields of the perforation process can be quantitatively explained using the binary collision theory. The main peculiarity of the interaction between the ion beams and the suspended 2D material lies...

Nanostructuring of YBa2Cu3O7-x films is a challenging task on a way to the high-quality YBa2Cu3O7-x nanodevices because of the sensitivity of YBa2Cu3O7-x thin films to the patterning process. In this work we report on a "cold" nanopatterning procedure used for the structuring of the ultra-thin YBa2Cu3O7-x films by focused ion beam etching with a specially developed protection layer, which can b...
We present the commissioning results of the MicroChannel-Plate (MCP) based, ion extraction and detection system currently in use for an experimental test stand aimed at demonstrating the operation of a leastinterceptive transverse beam profile monitor based on a planar supersonic gas jet. This monitoring design features least-interceptive operation under excellent vacuum conditions and provides...
The application of focused ion beam (FIB) machining in several technologies aimed at microstructure fabrication is presented. These emergent applications include the production of micromilling tools for machining of metals and the production of microsurgical tools. An example of the use of microsurgical manipulators in a circulatory system measurement is presented. The steps needed to transform...
The neutral beam injection (NBI) system is designed to provide the ion heating and current drive for the high performance operation and long pulse operation of the Korean Superconducting Tokamak Advanced Research (KSTAR). The KSTAR NBI consists of two beam lines. Each beam line contains three ion sources of which one ion source has been designed to deliver more than 2.5 MW of deuterium neutral ...
BACKGROUND Ion beam has been used in cancer treatment, and has a unique preferable feature to deposit its main energy inside a human body so that cancer cell could be killed by the ion beam. However, conventional ion accelerator tends to be huge in its size and its cost. In this paper a future intense-laser ion accelerator is proposed to make the ion accelerator compact. SUBJECTS AND METHODS ...
