bubble chamber

n.
An apparatus in which the movement and collision of ionizing particles is determined by the examination of trails of gas bubbles that form in the paths of the particles as they move through a superheated liquid.

bubble chamber

n
(General Physics) a device that enables the tracks of ionizing particles to be photographed as a row of bubbles in a superheated liquid. Immediately before the particles enter the chamber the pressure is reduced so that the ionized particles act as centres for small vapour bubbles

cloud′ cham`ber


n.
an apparatus containing a mixture of gas and vapor in which visible tracks of ions reveal the paths of charged particles through the mixture.

bub·ble chamber

(bŭb′əl)
A device used to observe the movements of charged atomic particles, such as ions. A bubble chamber consists of a container filled with a very hot fluid. The paths of the charged particles are visible as trails of bubbles in the fluid. Bubble chambers are considered more useful than cloud chambers, because the bubbles remain visible longer than the condensation clouds of cloud chambers do. Compare cloud chamber.

The relatively simple bubble chambers were invented over 60 years ago, in 1952, and were used to track charged particles like electrons and protons.
The PICO experiment at the Department of Energy's Fermilab uses a bubble chamber in a bid to detect weakly interacting massive particles (WIMPs), which are a hypothesized type of dark matter.
He retired from Brookhaven Lab after 35 years as the senior cryogenic technical specialist in charge of building the bubble chambers, aka atom smashers, from the 50's to the 80's.
In this sense, the dark matter detectors PICO bubble chambers use a superheated fluid target filled in a glass vessel [5, 6].
The conclusions of these studies lead us to have design principles to select a specific piezoceramic circular geometry with a radio-clean piezoelectric material that can be used in the next generation of dark matter bubble chamber detectors (PICO 500 L) [9].
Bubble chambers were divided into two categories (hydrogen and heavy liquid bubble chambers); the former ones (like the "80 cm" BEBC, 15-foot Flab, Argonne 30 inches, etc.) had the advantage that the target was well defined and static; the latter ones (Gargamelle, BP3, 15-foot Bubble Chamber, SKAT, etc.) had a bigger stopping power and were particularly suited to identify the nature of the secondary produced particles like electrons, gamma rays, and pions and kaons decays.
Works in his Turner exhibition - each of the four artists is invited to put on a display - included two virtually identical paintings, which differed only in the words scrawled across them describing simultaneous events through his-tory, called Bubble Chambers: 2 Discrete Molecules of Simultaneity.
Physicists and astronomers, though, deal with WIMPs and MACHOs, giants and dwarfs, and bubble chambers. Then, there are the subatomic particles called quarks, which figure prominently in physics and astronomy.
Bubble chambers (see 1953) had turned out to be very useful, especially for the detection of ultra-short-lived particles.
Such an arrangement, which ended reliance on photographed particle tracks in bubble chambers and inaugurated the age of electronic particle detection, allowed physicists to pinpoint individual particle trajectories with improved precision while handling hundreds of thousands of such events per second.
The bubble chamber (see 1953) was excellent at detecting ultra-short-lived particles.
