Moreno Posted February 18, 2020 Share Posted February 18, 2020 What dependency exist between electron beam density and speed of electrons in this beam? What methods could allow to increase beam density quite a much without increasing the speed of electrons? Link to comment Share on other sites More sharing options...

So, which law governs relation between unidirectional speed of electrons and the density of a beam? Why beams could become denser if electrons fly faster?
