6 Claims

1. A device for radiotherapy treatment with high dose rate of ionizing radiation for cancer patients, comprising:

at least one accelerating guide (11) of a radiofrequency accelerator of a charged particles beam, in which said accelerating guide (11) comprises an accelerating cavity, said particles being adapted to generate a magnetic field perpendicular to the axis of a current beam (13) of said charged particles; and

at least two resonant cavities (10); and

an optical system (20) of the beam;

wherein said at least two resonant cavities (10) being located upstream and facing said optical system (20), positioned perpendicularly to said magnetic fields and being tuned to a same resonance frequency which is equal to the working mode frequency of said accelerating guide (11);

wherein said at least two resonant cavities (10) comprising each respectively at least one second pick-up (12B) consisting of a coil;

wherein said at least two resonant cavities (10) and said respective at least one second pick-up (12B) are able to measure said current (13) which is proportional to the dose of a beam current absorbed by a target, said at least two resonant cavities (10) being made in order to measure independently said dose of beam current absorbed by the target;

wherein said device further comprising:

at least a first pick-up (12) consisting of a coil, which is comprised in said accelerating guide (11) and placed inside said accelerating cavity, in which said first pick-up (12) is positioned orthogonally to said axis of the current beam (13) and is able to measure in a non-destructive way a kinetic Energy of said charged particles beam and the flow variation of said magnetic field.
