Abstract

An electron cyclotron emission (ECE) heterodyne radiometer and a Thomson scattering (TS) system were used to measure the electron temperature (T_e) evolution in plasmas of the Rijnhuizen Tokamak Project (RTP) during the abrupt loss of energy confinement in high-density limit disruptions with unprecedented high resolution
