Abstract
Atomic beam probe is a new diagnostic method for detection of ions coming from the ionized part of diagnostic neutral beams in tokamaks. The method allows to measure plasma density fluctuations and fast variations in the poloidal magnetic field.
Therefore, one can follow fast changes in the edge plasma current. Test detector has been installed on COMPASS as an extension of lithium beam diagnostic and the article presents the first measurements done with the diagnostic.
