Study on improvement of injection power for EAST-NBI
Listed in ScienceDB
In order to meet experimental requirements on high parameter plasma research, the injected power of counter injector is expected to increase at a fixed beam energy of 50keV for deuterium neutral beam.
Description
Three candidate schemes are compared to assess the possibilities of raising the injection power. Consider safety and economic factors，raising the electric field in the first gap is employed by adjusting the voltage gradient on the accelerator.
The experiments show that the optimum perveance is increased from 2.2μP to 2.7μP by changing of gradient grid voltage from 0.84Vacc to 0.78Vacc. The ion beam power is promoted by about 50% at 3.0μP. But, beam transmission efficiency decreased to 60 % at 3.0μP. Thus, the injection power is boosted about 25%.
