Monte Carlo Study on Focus Properties of Portable Ultrabright Microfocus X-Ray Sources

         

摘要

@@ The construct and electrode potential of emitting systems are very important for the portable ultrahigh brightness microfocus x-ray sources. The ratio of Dw/H (Dw is the diameter of Wehnelt grid aperture and H is the setting height of the cathode) and the grid bias are determinative parameters for the emission current and focus properties of an electron beam.
