Abstract
- Reconstruction techniques have been developed to obtain 2-D images of high β plasmas by taking advantage of the large toroidal rotation rate on TFTR. The Shafranov shift, which is large in high β plasmas, is taken into account in the reconstructions. A 2-D image of the electron temperature is reconstructed from the electron cyclotron emission with the assumption of rigid poloidal rotation. The soft x-ray tomography is performed using the Fourier-Bessel expansion technique from two x-ray cameras. The reconstruction techniques are tested numerically through the use of model islands. The image is reproduced from the source function with these techniques; however, the x-ray tomography without rotation using the two cameras gives unacceptable results. [ABSTRACT FROM AUTHOR]
