Abstract
We have developed a long indirectly heated cathode (IHC) ion source with a multi-slit electrodes system. With this ion source, it is possible to stably extract a sheet beam with a height of 300 mm. The beam is extracted through the four electrodes, which are composed of three slits. The current density of the extracted beam is not high. However, because the extraction aperture area is large, we can obtain a high current ion beam. In addition, by using a new developed manipulator for electrodes that can move in four directions, the beam can be efficiently passed through the electrodes. Our high current implanter installed this ion source for material modification recorded the maximum beam currents for carbon at 0.5 keV, 1 keV, and 25 keV of 32 mA, 39 mA, and 51 mA, respectively.
期刊介绍:
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
