title: A proposal for improved helium microscopy.
abstract: Elimination of the electrostatic objective lens and alternative use of a Cc- and Cs-corrected quadrupole doublet may increase the useful working distance of the helium microscope, improve its resolution from 3 to 0.3 Å, and improve its optimum convergence angle from 0.4 to 4 mrad.
