WebNov 29, 2024 · Figure 6a shows the 3D trajectory of the electrons in the multiple beam tunnels, from which the obvious electron bunching can be found. Periodic electron density modulation occurs as the electrons with higher energy keep up with electrons with lower energy. Simultaneously, part of the electrons’ power is converted into high frequency power. WebFigure 2: Electron gun. The Bunching Section The bunching section has the purpose to compress the bunches in order to make the beam acceptable for the 3GHz wave of the accelerating structures. It is composed of a 499.654MHz subharmonic pre-buncher and a 3GHz buncher. The layout of the bunching section is shown in
