		bubble chamber, device for detecting charged particles and other radiation by means of tracks of bubbles left in a chamber filled with liquid hydrogen or other liquefied gas.
		The bubble chamber is particularly useful for studying high-energy particles that would pass through a cloud chamber too quickly to leave a detailed enough track but which pass more slowly through the bubble chamber because of the greater density of the liquid.
		Liquid hydrogen and helium are commonly used in bubble chambers, with special equipment needed to maintain these gases in their liquid state (see low-temperature physics).

	MCB Donald Glaser and his bubble chamber (1960)
		That was the basic idea behind the bubble chamber, a powerful instrument for the study of atomic particles that led to a 1960 Nobel Prize in Physics for its inventor, UC Berkeley professor Donald Glaser.
		Glaser first conceived of the bubble chamber in 1952, at the age of 25, while a faculty member at the University of Michigan.
		Over the years, bubble chambers increased in size--surrounded by a magnet the size of a bus to control the particles--and capability as scientists around the world embraced the instrument.

		Bubble chambers have played an important role in experimental particle physics, yielding images that can be beautiful as well as informative.
		The chamber, only 30 cm in diameter, was filled with liquid hydrogen - the simplest "target" material, as the nucleus of a hydrogen atom consists of a single proton.
		One of these was a neutral (uncharged) particle, which left no track, but revealed its existence when it decayed nearer the centre of the image, to produce two charged particles that leave behind a sideways V shape.

		As particles passed through the liquid, the volume of the chamber was rapidly expanded by a large hydraulic piston.
		This was the first particle detector of its type in which the chamber through which the particles passed was surrounded by a superconducting magnet.
		The following year, the 7-foot chamber was used to discover the charmed baryon, a particle composed of three quarks, one of which was the "charmed" quark.

	Bubble Chambers
		This was the principle exploited by Glaser in 1952 in the first bubble chamber, which proved of great importance in particle physics experiments for many years.
		A typical bubble chamber is filled with liquid hydrogen (forming a very simple nuclear target) at a temperature above the normal boiling point but held under a pressure of about 10 atmospheres by a large piston to prevent boiling.
		The liquid in the chamber acts as both target and detector, so bubble chambers cannot be used with modern colliding-beam machines.

		The bubble chambers were general-purpose detectors with which could be carried out a wide range of experiments over a considerable period of time, whereas the electronic counters were custom-built for a particular experiment and hence had a short active life.

	Bubble Chamber
		The bubble chamber is no longer in wide use for Particle Physics experiments, but the photographs that these machines produced are excellent for 'seeing' particles and the way that they behave.
		From a teaching point of view, the bubble chamber is a particularly valuable detector because it provides a real photograph of the trajectories of charged particles travelling though it.
		Once the photographs are taken (more than one view is needed to reconstruct the events in 3D), the bubbles are collapsed by recompressing the liquid, and the bubble chamber is prepared for the next burst of particles.

	CERN Courier - When the bubble chamber firs - IOP Publishing - article
		The advantage of the bubble chamber over the cloud chamber at accelerators was two-fold: the higher density of the liquid proportionally increased the number of interactions produced in it, and it was faster to reactivate, matching the frequency of the accelerator cycle.
		The chamber was a metal cylinder to which glass plates were attached, using indium ribbons as seals.
		Within a year the 10 inch (25 cm) hydrogen chamber of Alvarez was in operation at the Bevatron, which was then, with 5 GeV protons, the world's highest-energy accelerator, and which had permitted the discovery of the antiproton by Chamberlain, Segrè, Wiegand and Ypsilantis in 1955.

	What is particle physics
		Here we discuss the bubble chamber, a detector that was invented by Donald Glaser in 1952, and which served the particle physics community with distinction for about 40 years.
		Bubble chambers are particularly remembered for their enduring images, which not only have a beauty in their own right, but which also demonstrate in a believable way the `reality' of esoteric phenomena taking place in a few billionths of a second.
		The bubbles formed are allowed to grow for a few ms, and when they have reached a diameter of about 1 mm, a flash photograph is taken (on several views so as to enable the interactions to be reconstructed in 3-dimensions).

		The chamber would be filled with 240 gallons of super-cold liquid hydrogen, surrounded by a 31-ton magnet.
		The volume of the chamber was rapidly expanded by moving a 250-pound piston a mere half of an inch in 0.015 seconds, dropping the chamber pressure enough to make the hydrogen sensitive to the microscopic heat spikes caused by passing particles.
		The bubble tracks formed would be photographed by cameras which looked into the chamber through a 1,500 pound, polished glass window--the largest piece of lens-quality glass ever cast.

	bubble chamber
		The bubble chamber was developed in 1952 by the American physicist Donald A. Glaser.
		By taking high-speed photographs of these bubble tracks through the strong glass windows of the chamber, it is possible to make precision measurements of the details of nuclear processes caused by the high-speed particles.
		Because of the relatively high density of the bubble-chamber liquid (as opposed to vapour-filled cloud chambers) collisions producing rare nuclear events are frequent and are observable in fine detail.
