【 摘 要 】

Based on our previous work for proton transmission in nanocapillary, the simulation of hundred-keV protons through tapered-capillary was conducted. The deposited charge patch, small-angle scattering under surface as well as surface scattering were considered. We found, only the charge patch could not make the transmission effective. The charge-patch-assisted surface scattering make the density be enhanced.
