Abstract :
The velocity spread associated with phase mixing due to dc space charge in a magnetron injection gun (MIG) is investigated. A simple model is introduced to describe the mixing process. Simulations are performed by using the results of the EEGUN trajectory calculation for initial conditions at the entrance of the drift region. Results for a 170 GHz gun are obtained and compared with EGUN simulations. This new model provides a more accurate and efficient approach for analyzing the velocity spread due to mixing in MIG´s
