Abstract

This study reports the successful design, construction, and testing of a 200 keV electrostatic ion accelerator at NSTRI, emphasizing its beam transport performance and diagnostic capabilities. The system features a 13.56 MHz inductive RF ion source, a 200 kV high-voltage power supply, an acceleration section, a multi-component beam transport and diagnostic setup. Experimental results demonstrate a maximum beam current of 600 µA. Optimized beam dynamics, confirmed through simulations and experiments, yield focused beam profiles with RMS sizes of 4.2 mm (x) and 3.8 mm (y) at 150 keV. The diagnostic system, equipped with quadrupole and dipole magnets, enables precise measurement of beam current, divergence, emittance, and momentum spectrum. These results validate the accelerator performance, its agreement with simulations and its potential for advancing low-energy ion beam applications.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
