Improvement in the linear accelerators particles loaded

摘要

P linear accelerators which makes it possible to obtain particles accelerated in a wide range of energy without modification of the high frequency energy injected into the cavities of the accelerator structure. / p & & p & a system of the coupler - phase shifter w, receiving the signal w high frequency of a generator g, and comprising two waveguides w1 and w2 coupled together by means of a coupling aperture 8, makes it possible to inject respectively in the cross section and the accelerator k 1 and in the section buncher k2 signals w1 and w2 of amplitudes and phases, the phase shifting means (a plunger made of quartz, for example) is associated with the waveguide w2. / p & & p & linear accelerators provided with such a system coupler - phase shifter w can be used advantageously in the medical equipment radiotherapy treatment. / p
