Abstract
This paper describes spurious modulation effects commonly observed in electron tubes employing high current electron beams. The modulation is caused by positive ions and secondary electrons moving in the beam. It is eliminated by pumping the tube to high vacuum and retarding or deflecting the secondary electrons.Keywords
