The capacitively coupled radio frequency plasma at 13.56 MHz in oxygen was systematically studied by 160 GHz Gaussian beam microwave interferometry at high temporal resolution (200 ns) and simultaneous laser photodetachment for electron and negative

Low pressure capacitively coupled radio frequency plasmas (cc-rf plasmas) were investigated by minimalinvasive 160 GHz Gaussian beam microwave interferometry. The interferometer is a frequency stabilized (PLL) heterodyne system which immediately prov

In this series of two papers, the E-H transition in a planar inductively coupled radio frequency discharge (13.56 MHz) in pure oxygen is studied using comprehensive plasma diagnostic methods. The electron density serves as the main plasma parameter t

This contribution presents experimental results about the mode transition of an inductively coupled radio frequency (RF) (13.56 MHz) argon discharge at different total gas pressures. In particular, the positive ion saturation current and the line int

Instabilities in an asymmetric capacitively coupled radio frequency argon discharge occur within the pressure range of 70-100 Pa while adding low amounts of CF 4 . The development of these instabilities is highly dynamic in time and space. The instab

Periodic fluctuations in the frequency range from 0.3 to 3 kHz were experimentally investigated in capacitively coupled radio frequency (13.56 MHz) oxygen plasma. The Gaussian beam microwave interferometry directly provides the line integrated electr

Axial and radial profiles of the positive ion saturation current were measured by Langmuir probe diagnostics in a capacitively coupled radio frequency (RF) plasma in argon and oxygen. Under certain conditions these profiles provide the spatial densit
