http://www.ase-museoedelpro.org/Museo_Edelpro/Catalogo/Overview/Klystron%20Tubes.pdf WebWhen oscillations are present, an electron a, slows down transferring energy to oscillate. Such electrons that transfer their energy to the oscillations are called as favored electrons. These electrons are responsible for bunching effect. Case 2 In this case, another electron, say b, takes energy from the oscillations and increases its velocity. grand seas hostmark hurghada
