Repeatably aligned filaments are essential!
The beginning of the electron beam starts with the all important Filament.
To achieve the optimum working condition of the electron beam the geometric alignment from the filament to the workpiece must be correct. Therefore the positioning of the Filament is crucial.
The Filament Alignment Jig supplied with each new CVE machine aids the user by clamping the filament in a preset mechanical jig and ensures the filament position is aligned and repeatable.
This means the jig must be manufactured to a tight tolerance, tested and measured before it is fit for your use.
