Cryogenics for Big Science
Discover how Fermilab chills massive amounts of liquid argon to capture the universe's most elusive particles. This course prepares you for the engineering and operational challenges of the DUNE experiment.
Like Duolingo, but for Cryogenics for Big Science. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through The Liquid Argon Mission, The Cooling Loop, Purity and Safety Operations, and Cryogenic Foundations. It starts from scratch.

Key ideas in Cryogenics for Big Science
- Argon is much denser than gas, providing more atoms for neutrinos to hit
- Argon liquefies at approximately -186 degrees Celsius (87 Kelvin)
- Argon is transparent, allowing the light from particle collisions to reach sensors
- If the temperature rises above this point, the liquid will turn back into gas
- Why liquid argon is the preferred medium for neutrino detection
- The specific temperature required to maintain the liquid state
- The scale of cooling required for major experiments
- The role of electron drift in particle imaging
- Warming causes boil-off and pressure increases
- Temperature changes create bubbles or turbulence
- The consequences of failing to maintain a constant temperature
- The fundamental purpose and scale of the DUNE cryostat
- The function of the corrugated membrane design
- The outer support structure is the warmest layer
- Thick passive insulation sits between the support and the liquid
- Equipment must be small enough to fit down a narrow mine shaft
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Cryogenics for Big Science the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
