Brendan will be using a diffusion cloud chamber to make particles visible.
They will be viewable on a screen for audiences to see while Brendan will be on hand to discuss the process of making these naturally occurring particles visible.
The diffusion cloud chamber dates from 1936 and is used to study cosmic radiation and products of radioactive decay.
By creating a suitable atmosphere in the chamber, charged particles, by interacting with vapour, leave visible tracks.
These tracks can be analysed to provide information about charge and energy.
Three types of particles can be seen: cosmic radiation from the Sun, our galaxy and other galaxies in deep space and the results of its interaction with the Earth’s atmosphere; alpha particles from the radioactive decay of Radon gas coming from the decay of Uranium in the rocks all around us and decay products from manmade sources such as the Americium present in domestic smoke detectors.
This event is suitable for young people and adults. Phone: (053) 9196760 to book.
