a cryogenic switching element based on the property of semiconductors to abruptly change their conductivity under the influence of a critical magnetic field. The operation of a cryotron is analogous to that of a key or a relay; a cryotron may exist only in one of two states (the superconducting state or a state of low conductivity).
Cryotrons may be of the wire-wound or crossed-film (flat) type. The design of a film cryotron is shown in Figure 1. Cryotrons are capable of very fast response (the time of transition from one state into another is fractions of a microsecond); they are small (up to several thousand units per sq cm), inexpensive to produce, and highly reliable. As of 1973, because of engineering difficulties related to cryogenic cooling, cryotrons were at the stage of laboratory studies and experimental models.
