Abstract
Observations carried out with a laser-induced fluorescence diagnostic on several configurations of a multipolar discharge are presented. Thi s diagnostic allows very accurate measurements of the ion velocity dis tribution function in the argon plasma and reveals the presence of dou ble-hump velocity distribution functions due to ion acceleration in th e static plasma potential and ion reflection on a multipolar magnetic field. These observations give a new insight to ion temperature and io n drifts inside the device.
