Abstract :
A preliminary study of a very simple plasma central post ECR-assisted scheme synergetic to an ultra-low aspect ratio tokamak is presented. Stability issues are qualitatively discussed. An innovative particle fuelling is proposed for this tokamak plasma using the plasma centre post as a carrier. This fuelling scheme may naturally lead to an H-mode regime based on the direct analogy to experiments in several spherical tokamaks.
