When an ionizing particle enters the device, it collides with gas atoms and strikes electrons from their orbit around the nucleus of the gas atoms. In addition, an ionizing particle striking the outside of the tube can also knock electrons off the metal casing. In either case, these free electrons then are attracted to the positively charged central wire, gaining energy by the attraction. As they approach the wire they knock electrons off other atoms, creating an avalanche or cascade effect which results in a pulse of current large enough to be detected. A "quenching gas" is usually added to the filler gas so that these avalanches will dissipate over time and not continue indefinitely, which would cause inaccuracy or electronic failure.  1, fiche 2, Anglais, - quenching%20gas

Record number: 3, Textual support number: 1 DEF

A three-terminal semiconductor device exhibiting stable open-circuit, negative-resistance characteristics. The internal construction consists of a uniformly doped n-type, single-crystal semiconductor with ohmic contacts at each end and the emitter wire attached between them. It is ideal for use in simple precision relaxation oscillators that generate a short intense current pulse at the end of each cycle.  2, fiche 3, Anglais, - unijunction%20transistor

A method of sending a radio pulse down a wire or cable to detect a shorted or open condition. High-priced devices can pinpoint a fault within inches; lower-priced devices often provide widely varying results when they try to pinpoint the distance to a fault.  1, fiche 4, Anglais, - time%20domain%20reflectometry
