Measurements of Mode Converted Ion Cyclotron Wave with Phase Contrast Imaging in Alcator C-Mod and Comparisons with Synthetic PCI Simulations in TORIC

Mode converted ion cyclotron wave (ICW) has been observed with phase contrast imaging (PCI) in D-'He plasmas in Alcator C-Mod [1,2]. The measurements were carried out with the optical heterodyne technique using acousto-optic modulators which modulate the C02 laser beam intensity near the ion cyclotron frequency [3]. With recently improved calibration of the PCI system using a calibrated sound w...

Ion Cyclotron Range of Frequencies Mode Conversion Electron Heating in Deuterium-Hydrogen Plasmas in the Alcator C-Mod Tokamak

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 ...

Investigation of ICRF mode conversion at the ion-ion hybrid layer in Alcator C-Mod

Mode conversion (MC) of long wavelength fast electromagnetic magnetosonic waves (fast wave, or FW) into shorter wavelength electrostatic (ion-Bernstein, or IBW) or slow electromagnetic (ion cyclotron, or ICW) waves is of great interest in laboratory, magnetic fusion and space physics experiments. Such processes are particularly important in multi-ion species plasmas. In this paper we report rec...
