最初，介质壁加速器（DWA)是用于加速电子而非质子的。

At first, it was used to accelerate electrons rather than protons.

这套设备将由两个部分组成，每个部分都长12公里（7.5英里）.一部分是加速电子；

The machine would have two parts, each 12km (7.5 miles) long.

着重讨论尾流场的饱和机制以及电子参量不稳定性对产生尾流场和加速电子的影响。

We focused our discussions on the mechanism of saturation of the Wakefield and the electron parametric instabilities which affect the process of the Wakefield generation and electrons acceleration.

Now, if this incident energy is great enough it will take an electron out of the ground state and promote it.

现在，如果入射能足够的话,它会将一个电子从基态中释放出来,并且加速它。

What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.

前人们所做的就是他们说让我们确定,一个能量单位用来代表一单位电荷,加速穿过形成的一单位电势差，我们叫它电子伏特。

And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.

电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。
