Overview of MAST Neutral Beam System performance

This paper gives an overview of the MAST Neutral Beam System detailing both control and diagnostic capabilities. The operational experience of commissioning the beam line and the performance and characterization of the beams is described. Additional protection systems have been introduced and their design and operation are covered. Finally, future implementations to provide greater and more efficient performance are proposed, that will allow greater flexibility and configurability in the use of NBI in the MAST experimental program.
