WebFinally, the diffraction effects of a helium ion beam are con-siderably more favorable than those of an electron beam. A typical electron in a low voltage SEM has a momentum which is small enough that diffraction effects have to be accounted for. In com-parison, the ion in a helium ion microscope has a momentum which is 300× larger.
