DEVELOPMENT OF A PELTIER TYPE CLOUD CHAMBER WITH WIDE VIEW FIELD

Area of Science:

• Physics Education
• Nuclear Physics Instrumentation

Background:

• Cloud chambers are crucial for visualizing particle tracks in radiation education.
• Traditional cloud chambers often require dry ice for cooling, posing logistical and safety challenges.
• There is a need for more accessible and user-friendly radiation detection equipment for educational settings.

Purpose of the Study:

• To develop and evaluate a novel Peltier-based cloud chamber for radiation education.
• To create a portable and self-contained device that eliminates the need for dry ice.
• To enhance the observation of particle tracks for a wider audience, including students.

Main Methods:

• The study involved the development of a cloud chamber utilizing Peltier thermoelectric modules for cooling.
• A multilayered heat insulation system was incorporated to ensure a stable internal environment.
• The performance was assessed based on the clarity and visibility of particle tracks produced.

Main Results:

• The developed cloud chamber successfully produced sharp and visible particle tracks.
• The Peltier-based system eliminated the requirement for dry ice, simplifying operation.
• The chamber operated effectively without the need for a dark room, allowing for easier observation.
• A large observation window (12.5 cm diameter) facilitated group viewing for up to six students.

Conclusions:

• The Peltier-based cloud chamber is a viable and improved tool for radiation education.
• Its user-friendly design and dry ice-free operation make it suitable for classroom environments.
• The enhanced observation capabilities promote greater student engagement with nuclear physics concepts.
