Our EBD is based on the traditional tube design for anode grounded X-ray tubes. Therefore the cathode is on the HT side and needs to have negative polarity and additionally the filament supply on HT. These electron emitting tubes are electrostatic focalized only and provide extreme homogenious electron beam. The tubes are optimized starting from 90 kV up to 120 kV. The HT cable can be glued in for a maintenance free usage at the endusers side with very flexible HT cables up to 75 kV (up to 100 kV on special request). Standard cables with an R24 cone can be inserted directly into the tube receptacle.
