This type of racetrack microtron was developed in Canada by scientists at the University of Western Ontario. The world's 1st racetrack microtron was constructed there in 1961. The world's first microtron was constructed and operated at the National Research Council of Canada in 1947.

Fonction

An experimental model of the racetrack microtron type of electron accelerator, capable of producing beam of 18 million electron volts.

Technique

The racetrack microtron involved a new approach to electron accelerators. The racetrack geometry results in an instrument of smaller size & greater flexibility than the conventional microtron. This 3 cavity variable energy racetrack (or split-magnet) microtron with intra-sector beam focusing was one of a series of experimental racetrack microtrons built at the University of Western Ontario during the 1960`s & 1970`s. In 1961, the first successful microtron was completed at UWO, producing an energy beam of 6mev. In 1970 the University obtained a contract from Atomic Energy of Canada Ltd. to finance further developmental work. Construction was started on an accelerator that would demonstrate the feasibility of building compact multicavity racetrack microtrons with beam energies in the 15 to 40 mev range for radiation theraphy applications. It was completed late in 1972 & a year later the machine was sufficiently refined so as to achieve the values of beam current required by the design specifications. In operation, electrons are accelerated in 3 coupled cavities which give a boost of 1.5 to 3 mev upon each traversol. The magnets are large enough for 6 orbits so that a final energy of 9 to 18 mev can be obtained. (Brannen, pp.7-8).
