Abstract
The boundary element method is well suited to deal with some potential field problems encountered in the context of field emission. A bounda ry element method is presented in the specific case of three-dimension al problems with azimuthal symmetry. As a check, computed results are displayed for well-known theoretical examples. The code is then employ ed to calculate current from a field emission tip and from the same ti p with a protrusion. Finally an extension of the boundary element code is employed to calculate space-charge effects on emitted current.
