Peltier Cloud Chamber exposed to x-rays (extended version)

[GumokCZ]

The cloud chamber is so amazing machine...

perhaps you see photoelectric effect first, when the gamma ray energy become enough, you see compton effect, more energye (1,02Mev) and you can see pair production

Do you know the energy of the gamma ray for each voltage?

thanks for this rare video showing xray+cloud chamber

this shows how poorly understood the science of nucleation is. Specifically the tensile layer requires energy (endothermic if u want) and is a function of surface area. The other energy is latent heat of condensation (exothermic if u want) and is really a function of volume (but not in the traditional way) Anyhow for small droplets the surface area term prevails over the volume terms - result is small droplets requires energy to form and the xrays obviously provide it Kent
