Tools
Lightweight, in-browser calculators that let you explore the physics directly. Each states its assumptions and links to the series it accompanies.
- 3-flavour oscillation calculator Available Vary the PMNS mixing angles, mass-squared splittings, and L/E to plot oscillation and survival probabilities. For the Oscillations hub
- CEvNS cross-section plot Available Plot the coherent elastic cross-section versus neutrino energy and watch the N² scaling across target nuclei. For the Detection hub
- Schubart master-equation explorer Available Vary the flux, coupling, efficiency, and active volume to see how the modelled output power responds. For the Applications hub
- Mass ordering & flavour composition Available Switch between normal and inverted ordering and see each mass state’s flavour composition from the PMNS matrix. For the Oscillations hub
- Detector size comparison Available Compare neutrino detector target masses on a logarithmic scale — from kilogram CEvNS detectors to gigatonne IceCube. For the Detection hub
- Solar neutrino spectrum Available A schematic of the Sun’s neutrino components — pp, 7Be, pep, 8B, hep, and CNO — across energy. For the Sources hub
About these tools
Every calculator on this site runs entirely in your browser — nothing you enter is sent anywhere. Each one is a teaching aid built to make a piece of physics tangible: change an input, and the result updates immediately.
They are deliberately lightweight and state their assumptions, so they illustrate the behaviour rather than replace full research simulations. Each tool links to the deep-dive series it accompanies, and the underlying equations are gathered on the Formulas page.
If you are new here, the oscillation calculator is the most illustrative starting point; the CEvNS cross-section plot and detector comparison pair well with the Detection hub.
