内容記述
A several hundred keV class compact proton microbeam system was developed as a prototype of a 1 MeV compact microbeam system to be used in micro-fabrication and micro-analyses. Optimization of an extraction condition was performed to increase demagnification and to achieve a beam diameter of approximately 1 μm. The beam diameter measurement showed that a diameter of 1.8 μm was obtained. This indicates that the compact microbeam system is a feasible alternative to a MeV class conventional large accelerator system.
