Every second, hundreds of cosmic rays pass through your body — invisibly. The cloud chamber is the only device that lets you observe the imprints of the subatomic world with the naked eye.

The Beauty of Science

What is a cloud chamber?

The cloud chamber (Wilson chamber) is a particle physics detector invented by Scottish physicist Charles Thomson Rees Wilson in 1911, for which he received the Nobel Prize in 1927.

The device is a chamber filled with supersaturated alcohol vapor, in which ionizing radiation leaves visible condensation trails. You can observe with the naked eye the thick, straight tracks of alpha particles, the thin, winding paths of beta particles, and the long, traversing lines of cosmic rays.

Not a simulation. Not an animation. Real particles, in real time.

Behind the Science

How Does It Work?

01
PELTIER –30°C +20°C –30°C

Cooling

The bottom of the chamber is cooled to –30°C using a Peltier element cooler. This creates the supersaturated vapor inside the chamber. No dry ice needed — just a power source.

02
Vapor layer

Supersaturated Vapor Layer

Isopropyl alcohol vapor fills the chamber. A supersaturated zone forms above the cold layer — this is the medium in which particles leave their trails.

03
Ionization

Ionization

When a charged particle passes through the vapor, it leaves ions in its wake. These ions act as condensation nuclei — this is where the alcohol vapor condenses.

04
Visible tracks

Visible Tracks

The alcohol vapor condenses onto the ions — tiny droplets trace the particle's path. Visible to the naked eye, in real time! Alpha, beta, and cosmic rays each leave distinct tracks.

"The cloud chamber is a window of scientific discovery — where the invisible world becomes reality before our eyes."

— Charles Thomson Rees Wilson, Nobel Prize-winning physicist

What Do You See in the Chamber?

Particle Tracks

Alpha Particles

Thick, short, straight tracks. Two protons and two neutrons — helium-4 nuclei. They ionize strongly but have a short range.

α | He-4 nucleus

Beta Particles

Thin, winding tracks. High-speed electrons or positrons. They are easily deflected by atoms — hence the erratic path.

β | e− electron

Cosmic Rays

Long, traversing tracks. High-speed muons arriving from outer space. They cross the entire chamber — multiple times per second.

Frequently Asked Questions

It is not dangerous. The EduChamber package's Am-241 source (derived from smoke detectors) has extremely low activity, well below the exemption thresholds. The chamber also displays background radiation and cosmic rays — no additional source is needed for this. It can be safely used in a school environment.

The EduChamber and ScienceChamber packages use Peltier element cooling — no dry ice needed. It only requires a power source (230V). After turning on, it reaches operating temperature in 10-15 minutes and remains continuously operational.

Very well. The chamber's LED side illumination provides optimal contrast. In a dark room (with curtains drawn), the tracks are excellently visible. With the ScienceChamber package, the top camera + projector solution allows 30+ people to watch magnified simultaneously.

Yes. The EduChamber includes 12, the ScienceChamber 12, and the ResearchChamber 24 months of warranty. For the Pro and Research packages, on-site service within 48 hours is available. Remote support is unlimited for all packages.

Standard level: atomic physics, radioactivity, types of radiation (national curriculum). Advanced level: particle physics, cosmic rays, motion in magnetic fields. University: nuclear physics lab, particle physics practicum, detector technology. We include the experiment guide booklet and lesson plans aligned with the national curriculum.

Due to its size and ease of use, the EduChamber package is suitable for home scientific experimentation as well. However, it was primarily developed for educational institutions where teacher guidance and professional support are ensured.
