Pulser technology is often based on a switched capacitor bank in which a thyristor (historically a vacuum tube) switch is used to connect an energy storage capacitor to the load to
initiate the pulse and then disconnect it at the end of the pulse. Sometimes this is arranged into what is referred to as line type pulsers. The energy storage device is essentially a
lumped-constant transmission line108 and consists of a lumped element network approximating a transmission line. 126 This component of the line-type pulser is both the source of the electrical energy during the pulse as well as the pulse-shaping element and is generally referred to as the pulse-forming network. The design of a power supply for a high power pulsed magnetron sputtering is discussed by Christie et al.,115,127 Sproul et al.,128 and Kouznetsov.
