Abstract
Neutral beam injection in the START spherical tokamak induces L to H mode t ransitions in double null divertor configurations. The behaviour of the edg e poloidal velocity, electron temperature and density, and edge neutral den sity during the transition are examined. The region encompassing the therma l barrier is investigated with a variety of diagnostics including Doppler s pectrometry, Thomson scattering, a Balmer D-alpha camera and magnetics.
