Dark Matter colliding with an Argon atom
Numéro d’image : 11680541
| Simplified diagram showing the direct detection of a Weakly Interacting Massive Particle (WIMP,or dark matter,green),colliding with an argon atom. The collision produces both ionisation (blue) and scintillation (yellow) signals. Experiments using Xenon/Argon,currently searching for WIMPS include; SNOLAB underground laboratory in Sudbury; the Canfranc Underground Laboratory in Spain; the Deep Underground Science and Engineering Laboratory in South Dakota; and the Gran Sasso National Laboratory in Italy. Dark matter is a type of matter hypothesized in cosmology to account for effects that appear to be the result of mass where no such mass can be seen. Dark matter,theoretically making up 25% of the mass/energy of the universe,cannot be seen or directly detected; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level | |
