Description
When comparing PROCESS beam fusion calculations to METIS, I noticed therew was a large discrepancy.
After investigation, we can see that PROCESS applies a Bosch-Hale factor in the beam_fusion routine. Originally, beam fusion was using a correction based on a thermal D-T reactivity ratio. In practice, that meant the code was taking a beam-target fusion expression and multiplying it by a factor derived from thermal plasma reactivity.
This change removes the Bosch Hale-based correction factor from the beam-target fusion model and refactors the calculation into a clearer, physically consistent formulation.
Also there needed to be a re-factoring of the code itself.
