摘要
Two-dimensional (2D) time resolved images of the electron temperature profile in the core of the MST reversed field pinch plasma are presented. The measurements have been obtained with a soft x-ray (SXR) tomographic diagnostic comprised of four cameras, each with a multichannel photodiode array, viewing the plasma at different poloidal angles, with a total of 74 channels. The 2D electron temperature profile is estimated by simultaneously measuring the SXR emissivity through different beryllium foils, using the standard double-filter technique. With these methods, fast temperature variation in the core of the plasma (up to 100 kHz) can be analyzed. (c) 2006 American Institute of Physics.
