Plasma Engineering Laboratory
Available Equipment
PEL has decades of in-house expertise in the production, diagnostics and modelling of microwave-driven plasmas. This know-how is crucial to foster advances in the recently emerging cutting-edge field of Plasma Nanoscience, and enabling the proposal of novel plasma-based technologies.
The PEL team uses state-of the-art equipment for producing microwave plasmas and for its characterisation with optical diagnostics, mass spectrometry and probes. The most relevant equipment is shown below.
VUV range 8 – 32 nm (550 g/mm grating) and 30 – 125 nm (1800 g/mm grating) 2 diffraction gratings; PMT and VUV sensitive silicon detectors and its data acquisition.
