Beta Simulators & Tools
Larger simulators that are still in review. Each one runs a built-in self-test against published reference values, so you can see how it is tested before you rely on it. They stay out of search results until review is finished, and those that pass move to the main tools hub.
Beta, in review. Results are for exploration. Check numbers that matter against an independent calculation or measurement, and tell me about anything that looks wrong.
Ion Optics Workbench
Build electrode geometries, solve the electrostatic potential, and fly ions and electrons through lenses, mirrors, analyzers, and RF devices.
High vacuumConductance Lab
Conductance of tubes, slits, ducts, and whole pumping lines from molecular to viscous flow, and Monte Carlo conductance of CAD models.
Windows and coatingsGlazing Performance (Open Data)
The glazing calculator with measured glass optical constants, thin-film low-e coatings calibrated to published datasheets, and nine measured IGDB products, side by side with the current model.
Thermochemistry and photochemistryThermochemistry Lab
Bond energies, reaction enthalpies and photolysis thresholds from Argonne's Active Thermochemical Tables, with excited products, electron attachment, correlated uncertainties and energy diagrams.
