Description
A beam profile monitoring system based on the imaging of low energy electrons created when the ion beam impinges on a metal plate was built to cover the wide range of beam intensities and energies for the DESIREE (Double ElectroStatic Ion Ring ExpEriment) beam line diagnostics [1]. The spatial resolution of the system was tested for a H2+ beam of various energies and was found to be around 2 mm. For the lowest energy (3.5 keV), a significant steering effect on the ion beam before hitting the metallic foil was observed and found to be in good agreement with the SIMION calculations [2].
