摘要：

Neutral beam injector for EAST is designed to deliver deuterium beams with a powerof 2 MW to 4 MW at an energy of 50 keV to 80 keV into the plasma with a beam dimension of12 cm × 48 cm.Considering the beam generation and transmission,a columniform beam-lineof Φ 250 cm × 400 cm is designed with a neutralizer,ion dump,calorimeter,bending magnetand cryopanels.The arrangement of the internal elements for the beam-line is reported.Arectangular sleeve coupled to the ion source is employed as the neutralizer.At the downstream ofthe neutralizer,a dipole magnet separates the residual ions from the beam passage with a reflectionradius of 42 cm for the full energy particles.The calorimeter and the ion dump serve as high heatflux components,which will work as thermal inertia targets in the first phase of operation.
