Experimental Setup Fig. 1 shows the schematic diagram of the pulsed power generator used in this paper.
pulsed vacuum systems. In this work, the design of pulsed vacuum systems is thoroughly studied. During the process of designing and employing the pulsed vacuum system a method for calibration of a vacuum systems volume is described and how the system is used for plasma-less dry etching of Si using Xenon Diflouride (XeF2).
