The current-dependent beam divergence at a distance of 50 μm from an indium-liquid metal ion source is derived from experimental data obtained by measuring the beam spread with a 3D Plasma diagnostic system at a distance of 10 cm from the needle tip

We present a parametric numerical study conducted with the finite element code CasimirSim developed by ARC Seibersdorf research. This simulation has already been applied to two dimensional geometries in the past and showed agreement with exact theore
