| The present invention discloses an X-ray source which uses a rectangular cavity resonator, which is excited with a microwave TE10p mode. The present invention also can be used as a source of cyclotron radiation, using the cylindrical cavity, but carrying out some structural changes thereof to achieve this purpose. This system allows significantly increasing the energy of the electron beam by compensating the diamagnetic force by an axially symmetric electrostatic field. The electrostatic field is generated longitudinally by ring-type electrodes placed inside the cavity, preferably in the node planes of the TE11p electric field. The electrodes should be made transparent to the microwave field, such as graphite. | ||||||

| A charged particle beam transport system is characterized in that in a fixed transport unit, a phase of a phase space distribution of a charged particle beam at an inlet of a rotating deflection unit that rotates around an gantry rotation axle of a rotating gantry coincides with a phase determined by a calculation based on an average value of a first phase advance and a second phase advance. The first phase advance is defined as a change in a phase, of the phase space distribution, that changes when the charged particle beam travels from the inlet of the rotating deflection unit to an isocenter in the case where a gantry angle is a gantry reference angle; the second phase advance is defined as a change in a phase at a time when the gantry angle is pivoted by 90° from the gantry reference angle. | ||||||
