Oversized cloud chambers reveal frequent background
The sensitive volume of our Lecture Hall Chamber,
for example, is about 900 times that of the common “petri dish”
cloud chamber. In a chamber this large, natural background events create
a continuous parade of droplet tracks. Your students will find this quite
Introduce modern physics with a memorable display
Use our diffusion cloud chambers to visually present
atomic and nuclear processes. Reduce the amount of information your students
blindly accept by providing real time demonstration of individual charged
particle interactions with matter.
Promote student discussion of environmental
Show that ionizing radiation permeates everything
around us. Cosmic rays pass through all living things, creating genetic
change. Radon gas accumulates in many structures; it and its progeny decay
in our lungs. These sources are easily distinguished in our oversized
Show your students how radiation is absorbed.
Differentiate between tracks produced by artificial
sources including alpha, beta, gamma, and X-ray. Each type interacts through
different physical mechanisms, and our manual describes these in detail.
Your students will notice that alpha particles are stopped by a few cm
of air, and use external absorbers to observe the penetrating property
of gamma rays.
