S'Cool LAB Experiments

S'Cool LAB experiments - Header

Below you will find short descriptions of the experiments which are currently available in S’Cool LAB. You will find information about what students should already know before taking part in this experiment, what they will learn in S’Cool LAB, and how this knowledge is related to particle physics experiments at CERN. 

Cloud Chamber - Build and Observe a Particle Detector

Cloud Chamber

Description: Students build their own particle detector using dry ice and isopropanol to make cosmic particles and natural radiation visible. Students study the properties of the different tracks and discuss their observations.

Safety: Students must follow the safety rules specified by the S’Cool LAB team and use the appropriate safety equipment provided. This experiment involves working with dry ice (approx. -80°C), isopropanol at >90% concentration, and working with torches in the dark.

X-Rays - Medical Applications and Pixel Detectors

X-Ray unit

Description: Students operate an X-ray machine (35 keV) and study the absorption of X-rays in matter using a fluorescent screen and a pixel detector. 

Safety: The X-ray units in S'Cool LAB are fully protected devices and specially designed for use in schools. They present no danger from ionising radiation.

Electron Tube - The Basics of Particle Acceleration

Electron Tube

Description: Students operate an electron beam (300 eV) and study electrons in magnetic fields.

Safety: Power supply (300 V) will only be connected using safety leads, vacuum tube needs to be handled with great care.

Positron-Emission-Tomography (PET) - Medical Applications

Description: Students calibrate and use scintillation detectors to understand the basic principles of Positron-Emission-Tomography (PET) and locate a positron source (Na-22).

Safety: Radioactive sources (74 kBq Na-22) will only be handled by S’Cool LAB team. Nevertheless, pregnant women and students younger than the minimum age specified below are not allowed to take part in this experiment. The power supply (700 V) will only be connected using safety leads. Students must handle the fragile and expensive equipment with great care.

Superconductivity - Resistance is Futile

Superconductivity

Description: Students measure the electrical resistance of a normal conductor and a high-temperature superconductor (Bi-2223). They study the Meissner-Ochsenfeld-Effect and the Flux-Pinning-Effect.

Safety: Liquid nitrogen – used in the experiments – has a boiling point of approx. -196°C (77K). Liquid nitrogen will be distributed only by S'Cool LAB tutors. Some of the magnets used are very strong and must handled with care by the students.
