“…The calculation indicates that about 89.0% of beam power can be transmitted to the calorimeter. Experimentally the neutralization efficiency is about 60% for deuterium at 80 keV [4,8] . Thus, the neutral beam transmission efficiency is about 53.4% with the bending magnet on.…”

Theoretical beam intensity distribution is derived for the neutral-beam-injection ion source with a multi-slot extraction in EAST. The beam intensity profile, both along and perpendicular to the injecting direction and the beam power deposition to the inner elements in the neutral beam injector (NBI) are evaluated. The results indicate that the transverse beam intensity is much higher than the longitudinal one. This study could provide information for the design of vacuum system, structure of inner elements and cooling system of the neutral beam injector in EAST.
