A plasma windows viscosity allows it to separate gas at standard atmospheric pressure from a total vacuum, in fact it is reported that it can withstand a pressure difference of up to nine atmospheres.[2] At the same time, the plasma window will allow radiation such as lasers and electron beams to pass. This property is the key to the plasma windows usefulness — the technology of the plasma window permits for radiation that can only be generated in a vacuum to be applied to objects in an atmosphere.[3][4] One of the major applications of this technology is electron beam welding, where it has made EBW practical outside of a hard vacuum.
