# Theorical efficiency of Chirped Pulse Amplification HB11 fusion reaction

I read that scientists finally reproduced a more efficient fusion with a novel approach.

They accelerate hydrogen inside a pellet with a LASER. A single H atom produces three $$\text{He-4}^+$$ nuclei.

If employed directly, 3 nuclei means 3 x $$1.602 \times 10^{-19}$$ Coulomb of charge. So we need to keep $$0.2081^{19}$$ hydrogen atoms reacting every second to have a constant output of 1 Ampere.

The question that bugs me is, how many Amperes are necessary to accelerate that many H atoms within the boron using the Chirped Pulse Amplification laser to keep them reacting?
