Course detail

Plasma diagnostics

FCH-DCO_DIPAcad. year: 2011/2012

Course gives basic information about all metthods that could be used for the diagnostics of plasma and plasma processes. Besides various optical spectroscopic methods (emission, absorption, cavity ring down, laser induced fluorescence, actinometry) the spectroscopy of other electromagnetic radiation is disscussed. The next part is focused on various particle based diagnostics (mass spectroscopy, chromarography etc). The last part is focused on the measurement of electric characteristics and probe measurements.
