Query: Pellet fuelling with edge-localised modes controlled by external
  magnetic perturbations in MAST   The fuelling of plasmas by shallow frozen pellets with simultaneous
mitigation of edge localised modes (ELM) by external magnetic perturbation is
demonstrated on the MAST tokamak. Post-pellet particle loss is dominated by
ELMs and inter-ELM gas fuelling. It is shown that the size of post-pellet ELMs
can be controlled by external magnetic perturbations. Post-pellet ELMs remove
particles from the large part of pellet deposition zone including the area with
positive density gradient. The mechanism explaining this peculiarity of
particle loss is suggested.
