Schematic diagram of parallel plate ion chamber, showing creation of ion pairs, and drift of ions due to electric field. Electrons typically drift 1000 times faster than positive ions due to their smaller mass.[1]
English: Visualisation of ion chamber operation. An incident radiation particle leaves a trail of ion pairs in its path as it travels through the gas and collides with gas atoms. Each ion pair consists of a free electron, which is attracted to the anode, and a positive ion, which is attracted to the cathode by the influence of the electric field. This movement is known as "ion drift", and ensures that the electrons and positive ions do not recombine, and that an ionisation current is generated, proportional to the number of ion pairs created.

A publicity photo of a participant sitting in the Colorado Springs experimental station with his "Magnifying Transmitter". The arcs are about 22 feet (7 m) long. (Tesla's notes identify this as a double exposure.)
English: Publicity photo of Croat-Serbian-American inventor Nikola Tesla in December 1899 supposedly sitting in his laboratory in Colorado Springs next to his magnifying transmitter high voltage generator while the machine produced huge bolts of electricity. This image was created using "trick photography" via a double exposure. The electrical bolts were photographed in a darkened room. The photographic plate was exposed a second time with the equipment off and Tesla sitting in the chair. In his Colorado Springs Notes Tesla admitted the photo was a double exposure: To give an idea of the magnitude of the discharge the experimenter is sitting slightly behind the "extra coil". I did not like this idea but some people find such photographs interesting. Of course, the discharge was not playing when the experimenter was photographed, as might be imagined! and this is confirmed by Tesla biographers Carl Willis and Marc Seifer. In 1899-1900 Tesla built the laboratory and researched wireless electric power transmission there. The "magnifying transmitter", one of the largest Tesla coils ever built, with an input power of 150 kW generated voltages on the order of 12 million volts at frequencies around 150 kHz, producing 140 ft. (41 m) "lightning" bolts. Tesla sent a copy of this photograph to Sir William Crookes in England in 1901.
