Experiment Name Generator
Codenames for studies, trials and secret projects
Generate experiment names in the styles real scientists use: acronym trials like SPRINT and ASCOT, physics collaborations like ATLAS and IceCube, space and field campaigns, plus classified-sounding codenames for fiction and games.
About experiment names
Real experiments get named in a handful of recognizable ways. Physics collaborations favor bold acronyms and mythic single words (ATLAS, IceCube, DUNE, LIGO), often built backwards from a catchy word. Clinical trials do the same with a wink: SPRINT, JUPITER, RECOVERY, PARADIGM-HF, where the letters are made to fit and a hyphenated suffix names the disease. Long-running field studies are named for their place (Framingham, Hubbard Brook, Broadbalk, Park Grass), and space missions borrow gods and explorers (Apollo, Juno, Cassini, Voyager). Then there is the military tradition of two-word codenames chosen because they reveal nothing (Project Mogul, Operation Paperclip), which fiction has adopted wholesale.
This list mixes those registers. You'll find real landmark experiments (Michelson-Morley, Miller-Urey, the Stanford Prison Experiment) useful for citations and quizzes, real programmes and collaborations to model your own naming on, and invented codenames in the same style (Project Halcyon, Protocol Winter Salt, MERIDIAN-AF, Cherenkov Ridge Array) ready for a novel, RPG, or ARG. Field campaigns, invented probes and numbered runs (Tern Orbiter, Run 311) round it out.
For a real study, pick something a reviewer can pronounce and a search engine can find, and check the acronym isn't already a well-known trial. For a fictional one, pick a codename bland enough to be believable and let the horror or wonder come from the file's contents.
How to choose experiment names
- For a real trial or study, build the acronym from a memorable word first (BEACON, ANCHOR, PRISM) and then find words that fit; add a hyphenated suffix for the condition, e.g. LANTERN-HF.
- For classified-style fiction, use Project or Operation plus a neutral noun (Halcyon, Kestrel, Sundial) rather than something ominous; real codenames are deliberately boring.
- Physics and astronomy names lean on Greek myth, sky words, and instrument acronyms (Juno, Gaia, KATRIN); a fake collaboration reads real if it has a place plus an instrument, like Alpine Cosmic Ray Station.
- Field and ecology experiments are usually named for their site, so a place name plus what is measured (Highfield Soil Carbon Experiment) instantly sounds legitimate.
- Check ClinicalTrials.gov or a quick web search before adopting an acronym for a real study; duplicates cause confusion in the literature.
Frequently asked questions
How do scientists name experiments?
Common conventions include backronyms (SPRINT, ATLAS), mythological or celestial names for missions (Apollo, Juno), site names for long-term field studies (Framingham, Hubbard Brook), and neutral two-word codenames for secret or military projects (Project Mogul).
Are the experiments in this list real?
Some are real and historically important (Michelson-Morley, Human Genome Project, RECOVERY Trial); others are invented in the same style, such as Project Halcyon or MERIDIAN-AF. Real ones make good references; invented ones are meant for fiction, but none was checked against trial registers, so one may match a real study by chance.
Can I use these names for a science fair project or a novel?
Yes. The invented codenames are there to be used. For real experiment names, use them as references or inspiration; a school project should have its own descriptive title, and fiction usually reads better with a name that isn't tied to a real event.
What makes a good codename for a fictional experiment?
Two words, one of them a plain noun from nature, tools, or weather (Project Ironwood, Operation Coldwater), plus optional numbering like Experiment 47-B. Avoid names that spell out the twist; the blandness is what makes it feel authentic.
