150 years of particle accelerators at the ICB!
On April 4, 5 and 6, the ICB laboratory welcomed members of the accelerator division of the SFP for an unprecedented exhibition: discovering the world of particle accelerators through playful, spectacular or intriguing experiences.
Experiences
Maltese Cross
Reproduction of one of the historic experiments that led to the discovery of electrons: heating a piece of metal (cathode) and applying a high voltage. Appearance of an image which is sensitive to the magnetic field.
Superconducting Levitation I The Superconducting Train!
The train is filled with liquid nitrogen, at -196°C, which cools the disc inside until it passes into a superconducting state: the train then levitates above the rail magnets and can be pushed.
Van De Graaff Generator I An experiment that produces sparks!
The Van De Graaff generator makes it possible to accumulate electrical charges in a charged sphere isolated from the earth by an insulator. As charges accumulate, the electric voltage of the sphere rises to reach several thousand volts. If we approach a second sphere connected to the ground, an electric discharge is produced by creating a spark several centimeters long.
The round of electrons
This fun experience allows you to understand the basic principles of a circular accelerator of the storage ring / synchrotron type.
Inflating a vacuum balloon
A slightly inflated balloon is placed in a vacuum chamber. We then pump the air into the enclosure and we see the volume of the balloon increase: this demonstrates that the volume of the balloon does not depend on the quantity of air it contains but on the balance of the pressures on its walls.
Cloud chamber
A particle detector which shows in the form of contrails the passage of nuclear particles in matter.
