Localized direct electron heating by mode-converted ion cyclotron range of frequencies (ICRF) waves in D(H) tokamak plasmas has been clearly observed for the first time in Alcator C-Mod. Both onand off-axis (high field side) mode conversion electron heating (MCEH) have been observed. The MCEH profile was obtained from a break in slope analysis of electron temperature signals in the presence of ...
The observation of spontaneous islands growth in tokamak experiments indicates that the tearing mode could also be linearly unstable. However, in the framework of resistive magnetohydrodynamics, previous works have demonstrated that drift effects, electron heat transport along magnetic field lines and ion Larmor radius effects have stabilizing effects. Recently, numerical calculations and analy...
A brief description is given of an economical implementation of the read out of a two-dimensional detector in an electron spectrometer by a charge coupled device camera, using a pulse counting mode. Count rates up to 10 kHz can be handled in this way. A comparison with results obtained using a resistive anode detector is given for the case of electron scattering from Xe atoms. Good agreement wa...
