DIY cloud chamber material

Particles coming from the universe are crossing the earth all the time – they are harmless but invisible to us. Cloud Chambers are detectors which make the tracks of the particles visible. Some decades ago these detectors were used at CERN in the first particle physics experiments. The following...

Do-it-yourself cloud chamber

The cloud chamber is one of the oldest detectors for elementary particles. A simple type of a cloud chamber can be built with materials that are easy to purchase. This instruction shows how to build a cloud chamber and gives information on the traces left by particles as well as the particles...

This was one of the CERN workshops at the Expanding your Horizons event in Geneva (www.expandingyourhorizons.org/conferences/geneva/). Similar initiative than the one presented here:...

This is one of the workshops that CERN performed at the Expanding your Horizons event in Geneva (www.expandingyourhorizons.org/conferences/geneva/). It can be performed in any high energy physics outreach event illustrating...

"Dans la peau d'un chercher" or "Becoming a Scientist" is a program for primary schools in the Canton of Geneva, Switzerland and the neighboring Pays de Gex, France. The project aims to educate children from 9 to 12 years on what it is really like to be a scientist searching for answers to the...

The website provides a summary of how teachers, physicists, education staff and exhibit professionals designed and built a permanent exhibition about Fermilab's science and technology. The story we wrote to guide our work is posted as are descriptions and photos of all the exhibits.

This hands-on exhibit is part of the exhibition module #9 "The Big Bang in the Tunnel" of the exhibition 'Weltmaschine'. Created by DESY in Germany, it teaches how linear accelerators work. Exhibit visitors are invited to try the accelerator themselves.
It has been rebuilt (with small...

This hands-on exhibit is part of the exhibition module #9 "The Big Bang in the Tunnel" of the exhibition 'Weltmaschine'. Created by DESY in Germany, it teaches how large circular accelerators like the Large Hadron Collider work.
For more information on the exhibition or related exhibits,...

This hands-on exhibit is part of the exhibition module #6 "Where is the Antimatter?" of the exhibition "Weltmaschine". It teaches exhibit visitors how similar yet different matter and antimatter are by representing each with a box of sand.
The module consists of two transparent, containers...

This hands-on exhibit is part of the exhibition module #5 "What is the origin of mass?" of the exhibition 'Weltmaschine'. Built by TU Dresden and University of Würzburg.
Drawings can be obtained from Technische Universität Dresden (contact: Michael Kobel)
In this apparatus, paddles...

This hands-on exhibit is part of the exhibition module #6 "Where is the Antimatter?" of the exhibition "Weltmaschine". It explains the superposition of two stable states as the cause of particle-antiparticle mixtures.
For more information on the exhibition or related exhibits, see related...

For the project grenzgenial we developed this exhibit, which allows to interactively adjust the energy of the LHC. Displays inform about the current speed and energy of the protons, animations show the movement of the particles.
 
This model illustrates in a scientificly correct way...

This is the worldwide first model of coupled pendula, which demonstrates the complete phenomenology of neutrino flavor-oscillations for 3 different neutrino species (flavors). Up until now, only models for just 2 flavors existed.
The model is adjustable corresponding to variable neutrino...

The NBI Colliderscope is a light-artwork placed on the facade of the Niels Bohr Institute in Copenhagen. The work of art is connected directly to the world's largest physics experiment just outside Geneva, Switzerland.  The idea of the artwork is to create a direct sensuous and intuitive...

A hands on working model of a linear accelerator.  Model consists of a metal track, ball and computer/monitor which measures the ball's speed. A ball has to be given energy with exactly the right timing by lifting a part of its supporting track. At the end of the track a PC will measure its...
