What is Cloud Chamber?
 Cloud chamber also known as Wilson
Chamber is a historic devise used to make
charged tracks. Originally cosmic rays in
pre-accelerator times visible over a large
volume. It’s filled with gas.
How was it invented?
 This cloud chamber was
invented c. 1900 by C.T.R
Wilson.
 It was invented to study
formation of the clouds
produce when alpha&beta
particles traveled through
them.
 He won the Nobel prize
for Physics for his cloud
chambers.
 Using cloud chambers
we see the trails of
radioactivity particles.
What discoveries did it make
possible?
Bubble Chamber
 Bubble chamber is a devise for detecting
charged particles and other radiations by
means of tracks. Bubble left in a chamber
filled with liquid hydrogen or other
liquefied gas.
 It was invented in 1952 by Donald Glaser.
Spark Chamber
 Spark chamber is a device for recording the
passage of elementary particles produced by
reaction in a particle acceleration. Particles
pass through a stack of metal plates or wire
grids that contain high voltage between
alternate layers. It it replaced the bubble
chamber.
 It was most useful in searching for very rare
elements.
 It took the place of bubble chambers.
Bubble and Spark Chambers
 Physics have developed other particles
detectors, notably the bubble and spark
chambers which became widely used
in the study if radioactivity, X-rays, Cosmic
rays, and other phenomena today in the
world.
