论文摘要
我们介绍了可开关电子镜的设计和原型，以及一种用平顶脉冲驱动它的技术。我们采用了一种通用技术来进行电子脉冲形成，其中需要高脉搏形状的高保真度，但是系统的特性（可能是非线性）尚不清楚。该驱动技术使用任意波形生成器来预加密脉冲，并使用一种简单的迭代算法来生成输入波形。我们证明了在无偿波形上大约两个数量级的RMS误差的改善。这是一种广泛适用的任意脉冲塑形的通用方法。
We present the design and prototype of a switchable electron mirror, along with a technique for driving it with a flat-top pulse. We employ a general technique for electronic pulse-shaping, where high fidelity of the pulse shape is required but the characteristics of the system, which are possibly nonlinear, are not known. This driving technique uses an arbitrary waveform generator to pre-compensate the pulse, with a simple iterative algorithm used to generate the input waveform. We demonstrate improvement in RMS error of roughly two orders of magnitude over an uncompensated waveform. This is a broadly applicable, general method for arbitrary pulse shaping.
