Can a cloud chamber detect electrons?

(They may produce charged particles that can subsequently be observed, but this is much less common.) Cosmic rays can also be detected by cloud chambers, as the secondary rays formed in particle showers are ionising particles such as muons and electrons.

What particles are in a cloud chamber?

The charged particles which produce tracks in a cloud chamber are alpha and beta particles (from radioactive atoms), and protons and muons (from space). Alpha and beta particles come from radioactive materials in our environment: potassium, uranium and thorium in building materials and ground rocks.

What is a thermoelectric cloud chamber?

A cloud chamber consists of a super-saturated vapor inside a sealed chamber which forms visible trails of mist when radiation particles are emitted from a nearby source.

What is a cloud chamber a level physics?

In a cloud chamber, particles enter a magnetic field, and also a liquid which they ionise. This ionisation causes the paths of the particles to become visible. When the particle loses its charge, its track ceases. When the particle loses momentum, the radius of the circle decreases, and so, particles spiral inwards.

How does an ion chamber work?

The operating principle of an ionization chamber is simple: ionizing radiation from the source (X- or gamma rays, electrons) creates an ionization of the gas atoms. A voltage is applied between the electrodes. Negative charges are attracted by the anode, positive charges by the cathode.

What do cloud chambers let us see about particles?

Cosmic rays are high-energy subatomic particles that constantly bombard the Earth from outer space. Thousands of these particles pass through our planet, and through us, every second. This natural radiation is harmless and invisible, but the tracks that the particles leave behind can be seen using a cloud chamber.
