Runaway electrons in TEXT-U
Description
Runaway electrons have long been studied in tokamak plasmas. The previous results regarding runaway electrons and the detection of hard x-rays are reviewed. The hard x-ray energy on TEXT-U is measured and the scaling of energy with electron density, ne, is noted. This scaling suggests a runaway source term that scales roughly as ne/1. The results indicate that runaways are created throughout the discharges. An upper bound for Xe due to magnetic fluctuations was found to be .0343 m2/s. This is an order of magnitude too low to explain the thermal transport in TEXT, implying that electrostatic fluctuations are important in thermal transport in TEXT
