Description

In recent RFP plasma experiments, energetic electrons more than an order of magnitude higher than the local bulk electron temperature have been observed at the edge region by using Faraday cup, and it is discussed relating it to the Kinetic Dynamo Theory (KDT). In this paper we present the measurements related to the energetic electrons at the plasma edge of TPE-1RM15, mainly featuring its heat power flux loss fraction and estimation of the energy of the incident energetic electron. The latter was done by observing the soft X-ray emission from the fixed limiter and by inserted metal target material. These can give information about the energy distribution of the incident electron in the range over keV. (author) 6 refs., 6 figs
