UC Davis PDG:MHD Observations on TEXT-U

*

Shown above is the reconstructed electron temperature profiles during MHD activity on TEXT-U (shot #227444). 

For further technical details, and ECE Imaging measurements and results from TEXT-U, please examine the following links: 

*2-D temperature profiles
*2-D temperature images
*Temperature profile evolution during sawteeth activity
*Cross-correlation measurements of electron temperature fluctuations
*Temperature snakes observed during high power ECRH

The unique features of the ECE Imaging diagnostics derive from the use of wideband, low cost monolithic and hybrid Schottky diode mixer arrays. Follow the links below to learn more about both the technology and the techniques employed in ECE Imaging. 

*Imaging array design and fabrication
*Correlation Measurements

UC Davis has fabricated and installed multichannel ECE Imaging systems on other fusion plasma tokamaks across the world. Follow the links below for a description of the systems involved, and to sample data collected with these systems.
