Photon and Neutron Production as In Situ Diagnostics of Proton-Boron Fusion

Figure 4

Yield ratio of to for a normalized Maxwellian input proton spectrum in boron, comparing the yield with and without beam energy losses in the target. Target temperature makes a negligible difference to the energy loss for proton energies in this regime, and the  keV curve lies on top of the . Solid bands show the error propagated from the cross-section. Error bars, where visible, present the numerical error.
