The Academy
Vacuum science, made to play with.
Short interactive lessons. No paywall, no sign-up. Pick your level and start where it fits.
- 01 The Mean Free Path How far a molecule travels before it collides. Drag pressure and temperature, watch the path grow and shrink. Open →
- 02 Why We Bake Heat drives gas off the walls. Why every clean vacuum starts hot. Open →
- 03 Reading a Spectrum What the peaks mean, on a real residual gas scan. Open →
- 04 Pressure Signatures Air, water, oil, a leak. Learn the shapes pressure makes. Open →
- 05 Pumps & Conductance Why a bigger pump rarely solves the problem. Open →
- 06 The Quadrupole How a mass filter sorts molecules. Tune the fields, see what passes. Open →
