| Description: | The purpose is to make simultaneous measurement of density and temperature fluctuation level and radial correlation length in both low and high field side of an L-mode plasma, and compare with TGLF, GYRO predictions. | ||
| Experimental Approach/Plan: | Develop an L-mode plasma with appropriate Bt and density so that correlation reflectometer and CECE system can take measurements in both low and high field side. Take data together with BES in the low field side in repeat shots. Fluctuation data will also be collected with Doppler reflectometer, FIR scattering, PCI, and Langmuir probes, etc. | ||
| Background: | In the last run period for the first time simultaneous density and temperature fluctuation measurement using CECE and BES in the low field side was very successful. Expand this effort to high field side for the first time, which is achievable with CECE and correlation reflectometer will provide further test of predictions of modeling and simulations. | ||
