Description
Summary:With the Variocathode EB Gun series completed in 2004 and the fully digital control of High Voltage Power Supplies introduced in 2014, the focus of EB product development has now been directed to the BeamGuidance System. This year, the new VON ARDENNE BeamGuidance will be implemented for the first large EB melting furnace and EB production coater. Based on standard industrial hardware components, a completely new signal processor and HMI software was developed. Sophisticated procedures implemented on the signal processor calculate all dynamic beam scanning sequences for multiple EB guns in real time including automatic figure movements, coordinate transformations and dynamic corrections. Although the beam scanning sequences are defined with discrete coordinates, the new BeamGuidance allows for both quasi-digital (point to point) and analog (continuous) electron beam movement. With further new key features like synchronization of multiple beams, synchronization to external events and extended time and power distribution based figure manipulations, the new BeamGuidance System provides a new quality for control of EB processes.
