ABSTRACT
Presents an abstract of a paper focusing on the identification of Alfven mode location via multichannel interferometer measurements. Types of plasmas in which quasicoherent magnetohydrodynamics modes with an Alfven frequency scaling can be observed; Close correlation between the changes in the mode frequency and electron density measured by the interferometer.
