The point of formation of a cloud of electrons, caused by a particle ionizing a gas, is determined by timing the constant velocity drift of the cloud towards a fine wire anode, under the influence of an electric field. Drift chambers are used in high-energy gamma-ray telescopes for detecting photons by measuring the tracks of the electron-positron pair after a pair production absorption. |
