TJ-II disposes of two neutral beam injectors (NBI), each of which can produce ≤ 300 ms pulses of neutral hydrogen accelerated to 40 keV, to provide up to 1.2 MW of absorbed additional heating for central electron densities up to 1.6×1020 m-3. [1] [2] [3] [4] [5] [6]

NBI1 is located in sector D8. NBI2 is located in sector C1.
