带状注在高频率、高功率、大电流密度等方面具有很好的前景,且其平面形的结构对于多注集成来说极具优势。为此该文选取了相对便于多注集成的均匀磁场、Wiggler磁场和周期会切(PCM)磁场,使用微波管模拟器套装的电子光学模拟器对带状电子注的传输特性进行了研究。结果表明:均匀磁场下带状注可以稳定传输最远;随着带状电子注电流密度的增大,相对不易获取的磁场结构依次是PCM磁场(最难获得)、Wiggler磁场和均匀磁场;Wiggler磁场相对而言,是比较便于工程应用,并保证电流密度较大带状电子注可以稳定传输的最好选择。给出了Wiggler磁场3×3多注集成的模拟结果,其电流密度为110 A/cm2,该Wiggler磁场结构的凹槽可以使带状电子注在传输过程中具有一定的聚束效果,对于约束互作用后的电子注将有良好的效果。
Ribbon Note has good prospects in high frequency, high power, high current density, etc., and its planar structure for multi-injection integration is extremely advantageous. For this reason, we selected the uniform magnetic field, Wiggler magnetic field and periodic magnetic field (PCM) magnetic field that are easy to integrate with multiple injectors. The transmission characteristics of banded electron injection was studied using the electronic optical simulator of the microwave tube simulator. The results show that the band-shaped charge can be transported farthest stably under a uniform magnetic field. With the increase of the density of the strip-shaped electron injection current, the relatively hard to obtain magnetic field structures are PCM magnetic field (hardest to be obtained), Wiggler magnetic field and uniform magnetic field, Wiggler Relatively speaking, the magnetic field is more suitable for engineering applications, and to ensure that the current density of the ribbon electron injection can be the best choice for stable transmission. The simulation result of Wiggler magnetic field 3 × 3 multi-injection integration is given, the current density is 110 A / cm2. The groove of the Wiggler magnetic field structure can make the ribbon electron injection have some bunching effect during the transmission. For the constraint Electronic interaction after the injection will have good results.
