速度不同的带电粒子经过耦合有大功率高频信号的真空加速腔时将受到速度调制，最终粒子的速度趋于一致。即如粒子1以V1，粒子2以V2的速度在束线中运动，其中V1小于V2，经过相同的时间，粒子2到达高频信号的负半周期，粒子1到达高频信号的正半周期，二者都受到由电场力产生的加速度a的作用，由式1-1可知经过相同的时间，粒子速度趋于一致，以达到改善束流的品质。

高频发射机系统如图2所示，主要由高频放大、槽路、冷却系统和供电系统四部分组成。高频放大部分是由固态宽频带放大器、电子管构成的二级放大系统;供电系统主要负责电子管的灯丝、栅极、帘栅极、阳极和宽频带放大器的供电;加之整个发射机是一个以分布参数为主的系统，因而槽路是改善发射机参数和性能的重要组成部分。考虑到发射机工作在一个有高压、低压、交流、直流、脉冲和模拟信号混合的电磁环境中，为保证控制系统的稳定性和可靠性，采用了西门子S7-300系列的PLC、触摸屏，并结合Ethernet(工业以太网)技术设计了NB2发射机控制系统，实现了发射机的远程控制。

Ethernet网络是采用商业以太网通信芯片和物理介质，利用以太网交换机实现各设备间的点对点连接的工业以太网技术。能同时能支持10M和100M的以太网的商业产品。它的一个数据包最多可达1500字节，数据传输可达10Mbps或100Mbps;从而实现数据的高速传输。

Charged particles with different velocities will be modulated when they pass through the vacuum accelerator chamber coupled with high power high frequency signal, and the final velocities of the particles will be consistent. In other words, if particle 1 and particle 2 move in the beam at the speed of V1 and V1 is less than V2, after the same time, particle 2 reaches the negative half period of the high-frequency signal, and particle 1 reaches the positive half period of the high-frequency signal, both of them are affected by the acceleration a generated by the electric field force. It can be seen from equation 1-1 that after the same time, particle speeds tend to be the same. In order to improve the beam quality.

The high frequency transmitter system, as shown in Figure 2, is mainly composed of four parts: high frequency amplification, trough, cooling system and power supply system. The high frequency amplifier part is a two-stage amplifier system composed of solid-state broadband amplifier and electron tube. The power supply system is mainly responsible for the power supply of the filament, grid, screen grid, anode and broadband amplifier of the electron tube. In addition, the whole transmitter is a system based on distributed parameters, so the channel is an important part of improving the parameters and performance of the transmitter. Considering that the transmitter works in an electromagnetic environment with high voltage, low voltage, AC, DC, pulse and analog signals mixed, in order to ensure the stability and reliability of the control system, Siemens S7-300 series PLC, touch screen, and combined with Ethernet(Industrial Ethernet) technology designed the NB2 transmitter control system. The remote control of transmitter is realized.
