a The voltage of the accelerating grid on tangential neutral beams 1 and 3 as a function of time. b Time evolution of line-integrated B4+ intensity reflecting the amount of boron in the plasma. c Alpha particle detector pulse count rate (black) with error bars due to Poisson counting errors (gray) and calculated p11B fusion rate (red) with error bars due to propagated uncertainty in beam energy (pink), scaled to match near t = 5 s.
