Apparatus for detecting sub-atomic particles

摘要

Apparatus comprises a colloid suspension (14) of charged particles such as silica, aluminium oxide or magnetite in a liquid, and electrodes (10) in contact with the colloid. The electrodes detect perturbations to electric fields caused by interaction between the charged particles and the sub-atomic particles, such as cosmic rays, muons or neutrons. The location of events is detected by using an array of electrode strips in a container (18) with a cover (20) transparent to the radiation of interest.
