Abstract
An electron beam shaping unit for use in electron beam column and a method for designing thereof is presented. The electron beam shaping unit is configured for affecting electron beams of high density or strong electron-electron repulsion. These 5 beams can always be modeled with multi electron wave function. The electron beam shaping unit comprises a mask unit configured for affecting propagation of electrons therethrough to thereby form a propagating electron beam having, at far field, radial shape as determined by multi-electron non-linear function being an eigen function determined by a multi-electron Hartree-Fock Hamiltonian.
