| 1. | Due to applying double beams , the velocity spread is lower because of smaller influence of space charge compared with single beam mig . in the interaction region this beam is easy to start oscillation and reject mode competition effectively 与单注磁控注入枪相比,双注枪可以提供速度零散小、高束流的电子注,在互作用区更容易起振,且能更好的抑制模式竞争。 |
