A plasma window (PW) is a device for separating two areas of differentpressures while letting particle beams pass with little to no loss. It has beenintroduced by A. Hershcovitch. In the course of this publication, theproperties of a PW with apertures of 3.3 mm and 5.0 mm are presented.Especially the link between the pressure properties relevant for applicationsin accelerator systems and the underlying plasma properties depending onexternal parameters are presented. At the low pressure side around some mbar,high-pressure values reached up to 750 mbar while operating with volume flowsbetween 1 slm and 4 slm (standard liter per minute) and discharge currentsranging from 45 A to 60 A. Unique features of the presented PW includesimultaneous plasma parameter determination and the absence of ceramicinsulators between the cooling plates. Optical analysis reveals no significantdamage or wear to the components after an operation time well over 10 h,whereas the cathode needle needs replacement after 5 h.
