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

Figure 5

Ratio of photon yield to yield in a quasi-thermal plasma as a function of proton mean kinetic energy. At left for the reaction and at right for the reaction. The yield increases rapidly as the mean kinetic energy nears the CM energy corresponding to the threshold for the cross-section (of Figure 1) and then plateaus. Different curves correspond to different boron to proton kinetic energy, showing that the yield is only sensitive to the relative kinetic energy if the boron mean kinetic energy is much less than the proton mean kinetic energy. Error bars, where visible, present the numerical error.
