During the radiation therapy with electron beam, due to electron interaction and scattering from structures of the head of the medical linear accelerator, unwanted photons are produced. The main contribution of the photon contamination is resulted from the various components of the medical linear accelerator on the way of the high energy electron beam, and few percent is due to the interaction ...
Communicated b y y. D. Cockcroft; MS. ABSTRACT. Acceleration of electrons by means of an electroma,onetiic wave travelling down a circular corrugated tube is considered. The relevint properties of corrugated tubes are derived and the factors influencing electron enxgies. Some numerical results are also quoted for a wavelength of 10 cm. The problems of high energy accelerators arc &scussed brief...
About 50% of the ten thousands particle accelerators at present running in the world are devoted to medical applications. The main areas of use are: (i) radioisotope production, (ii) conventional radiotherapy with electron and photon beams, (iii) oncological hadrontherapy. In this review paper it is shown that in all these areas there are new developments which are scientifically interesting an...
