Temporal evolution of the energetic ion velocity distribution at switch on of neutral beam injection (NBI) and the slowdown after switch off of NBI are measured. The turn on phase of the NBI has, furthermore, been measured in plasmas with a range of electron densities and temperatures. All of these measurements are shown to be in good agreement with simple Fokker-Planck modelling. Bulk ion rotation velocity is also measured.}, year = {2007}, journal = {Plasma Physics and Controlled Fusion}, volume = {49}, number = {12B}, pages = {B551-B562}, month = {Dec}, isbn = {0741-3335}, url = {://000252745900054 }, note = {ISI Document Delivery No.: 256QYTimes Cited: 0Cited Reference Count: 47}, language = {English}, }
