Argon plasma in the nano-PSI vessel

nano-PSI is a device at the Dutch Institute For Fundamental Energy Research (DIFFER). It is used for experimental physics research. PSI stands for Plasma Surface Interactions.


The subtrate is held at a substrate holder in position in a low-pressure vessel. Due to the plasma created using a Cascaded Arc Plasma Source,[1] an energetic partical flux arives at the surface of the substrate. This enhaces surface modifications, Plasma processing.

The subbstrate holder can be biased and heated or cooled. A capacitor bank can be used to create large heat fluxes. Gasses like Helium, Nitrogen, Argon, Xenon can be used as a process gas. A Langmuir probe[2] can be used for termining plasma conditions.
