Beam Imaging Solutions is developing a new compact Retarding Field Energy Analyzer (RFEA) that will be available soon for purchase. The new Model RFEA-1 is of a collimated entrance aperture design with 3 grids. One grid will be for sweeping a retarding voltage and the other two grids for electron suppression before and after the sweeping grid. The RFEA-1 will mount to a standard 2.75” conflat flange and will have similar outer dimensions like our model BOS-18 Beam Observation System. This new instrument can be used to measure the mean energy and energy spread of the incoming ion beam with beam energies up to 5keV. A separate version, the model RFEA-2 will have the capability of measuring beam energies up to 10keV and will mount to a standard 4.5” conflat flange with outer dimensions similar to our BOS-25 Beam Observation System. Both units should be available sometime in 2022.
