介绍了一种典型的高真空蒸发系统，讨论了将靶材加热到蒸发温度的三种方法（电阻加热、感应加热和电子轰击加热）。详细比较了各种电子轰击构型。描述了各种厚度测量技术的相对优点。介绍了自支撑箔的制作和安装过程，重点介绍了用作靶背衬和剥离箔的薄自支撑碳箔的制备。描述了各种目标背衬和更常用的脱模剂的优点。更困难的元素目标的准备进行了讨论，并提出了一个全面的清单的共同目标。
A typical system for high-vacuum evaporation is described and the three methods of heating the target material to evaporating temperatures are discussed (i.e. resistance heating, induction heating and heating by means of electron bombardment). Various electron bombardment configurations are compared in detail. The relative merits of various thickness measuring techniques are described. Stages in the fabrication and mounting of self-supporting foils are described, with emphasis given to the preparation of thin self-supporting carbon foils used as target backings and stripper foils. Various target backings, and the merit of the more generally used release agents are described. The preparations of more difficult elemental targets are discussed, and a comprehensive list of the common targets is presented.
