| Abstract: | The nature of the transverse magnetic fields of multi-beam PPM focusing system and its effects on beam focusing were discussed in theory.The PPM focusing system for a five-beam traveling- wave tube was simulated,and the transverse magnetic fields and the effects of coupling slot were analyzed. Beam displacement caused by transverse magnetic fields was illustrated by particle-in-cell simulation. |
