The correlation Doppler reflectometer system consists of two 50-75 GHz reflectometers with a selectable O/X-mode polarization. Launching from the same tilted antenna allows the measurement of the radial electric field shear dE/sub r//dr and radial correlation lengths L/sub r/, important parameters characterizing plasma turbulence. The reflectometer hardware(More)
The interaction of turbulence with stationary and oscillating zonal flows is important for understanding the behaviour of turbulent transport in magnetically confined plasmas. Doppler reflectometry has been used on the ASDEX Upgrade tokamak to measure profiles of Er, its fluctuations and density turbulence properties such as radial correlation lengths Lr(More)
Many factors influence and determine the quality and reliability of inkjet-printed MIDs. Therefore a holistic view and understanding of the process chain is of importance. Even though different limiting factors have been evaluated partly by previous research, a systematic examination on three topics along the whole process chain is presented in this work(More)
