【 摘 要 】

It was proposed to develop the biperiodical accelerating structure with operating frequency of 27 GHz to assess the possibility of design a compact accelerating structure for medical application. It is necessary to do the more careful simulation of variation characteristics this case because of decrease of wavelength 3-10 times in comparison with conventional structures 10 and 3 cm ranges. Results of such study are presented in the article. Also a combination of high electromagnetic fields and long pulses at a high operating frequency leads to the temperature increase in the structure, thermal deformation and significant change of the resonator characteristics, including the frequency of the RF pulse. Development results of three versions of system of temperature stabilization also discuses.
