  2. Cloud chamber - Wikipedia

    en.wikipedia.org/wiki/Cloud_chamber

    A cloud chamber, also known as a Wilson chamber, is a particle detector used for visualizing the passage of ionizing radiation. A cloud chamber consists of a sealed environment containing a supersaturated vapor of water or alcohol .

  3. Gilbert U-238 Atomic Energy Laboratory - Wikipedia

    en.wikipedia.org/wiki/Gilbert_U-238_Atomic...

    Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.

  4. Particle detector - Wikipedia

    en.wikipedia.org/wiki/Particle_detector

    In experimental and applied particle physics, nuclear physics, and nuclear engineering, a particle detector, also known as a radiation detector, is a device used to detect, track, and/or identify ionizing particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator. Detectors can measure the ...

  5. Renninger negative-result experiment - Wikipedia

    en.wikipedia.org/wiki/Renninger_negative-result...

    In Renninger's 1960 formulation, the cloud chamber is replaced by a pair of hemispherical particle detectors, completely surrounding a radioactive atom at the center that is about to decay by emitting an alpha ray. For the purposes of the thought experiment, the detectors are assumed to be 100% efficient, so that the emitted alpha ray is always ...

  6. Ark: Survival Evolved - Wikipedia

    en.wikipedia.org/wiki/Ark:_Survival_Evolved

    Ark: Survival Evolved (stylized as ARK) is a 2017 action-adventure survival video game developed by Studio Wildcard. In the game, players must survive being stranded on one of several maps filled with roaming dinosaurs , fictional fantasy monsters, and other prehistoric animals, natural hazards, and potentially hostile human players.

  7. Delta ray - Wikipedia

    en.wikipedia.org/wiki/Delta_ray

    Collectively, these electrons are defined as delta radiation when they have sufficient energy to ionize further atoms through subsequent interactions on their own. Delta rays appear as branches in the main track of a cloud chamber (See Figs. 1,2). These branches will appear nearer the start of the track of a heavy charged particle, where more ...

  8. Mott problem - Wikipedia

    en.wikipedia.org/wiki/Mott_problem

    Intuitively, one might think that such a wave function should randomly ionize atoms throughout the cloud chamber, but this is not the case. The result of such a decay is always observed as linear tracks seen in Wilson's cloud chamber. The origin of the tracks given the original spherical wave predicted by theory is the problem requiring ...
