Laboratory 01 · Reactivity and zero-dimensional balance

FusionSim

Integrates the published proton–boron-11 cross section over a Maxwellian relative-energy distribution to give reactivity, reaction-rate density and fusion power, then balances that source against bremsstrahlung and thermal transport for the plasma composition you enter.

41-point Sikora–Weller evaluationMaxwellian rate integralrelativistic bremsstrahlung fithomogeneous zero-dimensional
Method: reactivity is the Maxwellian average ⟨σv⟩ = √[8/(πμ)] (kT)−3/2 ∫ σ(E) E exp[−E/(kT)] dE, evaluated over 41 published evaluation points with log–log interpolation and segment boundaries at every tabulated energy. Fusion power uses Q = 8.68193 MeV at uniform volume density. Every result lists the channels included in its balance.

Result

Run a scenario to calculate rate, power, composition, losses, numerical agreement, and validity.

Sweep comparison

Run a sweep to compare fusion, radiation, and accounted confinement loss.

Published cross-section input

Model contract

Included equations

Distinct-species Maxwellian reactivity, R = npnB⟨σv⟩, Q-value power, quasineutral composition, Putvinski electron-ion/electron-electron bremsstrahlung, Maxwell–Jüttner electron plus nonrelativistic-ion thermal inventory, and U/τE.

Deliberately not included

Spatial profiles, kinetic tails, beam-target fusion, alpha slowing-down, ash, impurities, synchrotron radiation transport, line radiation, burnup, MHD/kinetic stability, plasma sustainment, magnets, walls, drivers, auxiliaries, or electricity conversion.

Source domain

The published measurement-derived cross-section table spans approximately 137.423–3480.855 keV centre-of-mass after exact invariant-s conversion from the published 0.15–3.80 MeV laboratory axis. No local extrapolation is performed. Qualification also requires Trel ≥ 100 keV; only 200–500 keV has the release’s V2 published-curve benchmark.
