Abstract :
The effects of space-charge field on velocity spread in the drift tube regions of gyro devices which use either magnetron injection guns (MIG) or Pierce gun/wigglers (PW) are investigated using computer simulation codes. It is shown that changes in velocity spread occur while the beam makes a transition from an essentially coherent laminar state to an incoherent mixed state.
