The Experiments, methods and results of obtaining micron beam in the MicrobeamFacility of the Institute of Plasma Physics were discussed in this paper. The H2+ beam wasaccelerated by the Van de Graaff electrostatic accelerator, and the collimator at the end of thebeam line is a 60μm thick stainless steel chip. And as a result, particle tracks on the solid trackprobes (CR39 film) etched in the solution of NaOH showed that the beam can go through thecollimator with a small aperure (2000, 300, 55, 30, or 10 μm) and 3.5 μm thick vacuum film(Mylar). Besides the CR39 method, the beam was measured by an energy spectrum detector afterthe 10μm diameter aperture and the 3.5μm thick vacuum film too.
