Cloud chamber (Wilson chamber) Observe decay of atom.

Description

Lot of one Cloud chamber.
It is rare equipment from last age used in
educational classrooms (physics experiments) to visualization radioactivity of natural minerals and uranium ore. For run this chamber you need
source (uranium mineral or other alpha-source)
and a little bit of alcohol.
NO dry ice and NO cooling like for other cloud chambers.
On images you can see tracks by alpha-particles from uranium ore and from alpha-source (smoke detector source).
The
Cloud chamber (also called Wilson cloud chamber) is a particle detector used for detecting ionization radiation and visualization charged particles.
In its most basic form, a cloud chamber is a sealed environment containing a supersaturated vapour of water or alcohol. When a charged particle (for example, an alpha or beta particle) interacts with the mixture, the fluid is ionized. The resulting ions act as condensation nuclei, around which a mist will form (because the mixture is on the point of condensation). The high energies of alpha and beta particles mean that a trail is left, due to many ions being produced along the path of the charged particle. These tracks have distinctive shapes (for example, an alpha particle's track is broad and shows more evidence of deflection by collisions, while an electron's is thinner and straight). When any uniform magnetic field is applied across the cloud chamber, positively and negatively charged particles will curve in opposite directions, according to the Lorentz force law with two particles of opposite charge.
To see
the tracks
of alpha
particles
need to pour
a few drops
*
of
alcohol into the pump.
Connect pump to the chamber  and push on pump few times. In the chamber
is formed
high
vapor pressure of
alcohol at
the pushing on
pump.
Supersaturated
alcohol vapor
will be formed when
the pump
will released
.
At this point
you can
see a lot of
lines -
tracks
of alpha
particles.
* -
I added
about
0.1ml
of alcohol into the
hand pump
.
And tracks
began
appearing
after
few push-release cycles (see images)
Minerals, source and few drops of alcohol not included.
S
hipping with tracking via airmail.
