Abstract: The present invention relates to a pulsed beam particle accelerator which can be used for particle radiation therapy. More particular, a device and method are provided to control the number of particles within a beam pulse. The particle accelerator comprises means for varying the number of particles within each beam pulse of said pulsed ion beam from a minimum value to a maximum value as function of the value of a beam control parameter. For each particle irradiation the required number of particles for each beam pulse is controlled by defining a value for said beam control parameter based on calibration data.

Abstract: The invention relates to a cyclotron which can produce a beam of accelerated charged particles that are intended for the irradiation of at least one target (200). The inventive cyclotron consists of a magnetic circuit which essentially comprises: an electromagnet with at least two poles (1, 1′), namely an upper pole (1) and a lower pole (1′), which are disposed symmetrically in relation to a mid-plane (110) which is perpendicular to the central axis (100) of the cyclotron and which are separated by a gap (120) containing the circulating charged particles and return flux (2) in order to close the aforementioned magnetic circuit; and a pair of main induction coils (5, 5′) which are used to create an essentially-constant main induction field in the gap between poles 1 and 1′. The invention is characterised in that it comprises means of centring the above-mentioned beam, consisting of at least one pair of bucking coils (6, 7) which are supplied by an electrical source (8) and which can modulate the intensity of the main induction field produced by the main coils (5, 5′), in order to increase the intensity of the induction field in a first area of the cyclotron and to reduce the intensity of the induction field in a second area of the cyclotron, which is diametrically opposed to the central axis (100) of the cyclotron.

Abstract: A device for varying the energy of a particle beam extracted from a fixed-energy particle accelerator includes a block of energy degrading material positioned in the path of the particle beam. The block of energy degrading material is preferably in the form of a ring arranged on a wheel. The ring is of a staircase configuration, having discrete steps defining a thickness between parallel entry and exit faces. According to one aspect of the invention, the block is configured so that the particle beam energy variation reaches a maximum at the edges of each step. This upper limit is also the lower limit of the next step. Thus, continuous energy variation is possible despite the fact that the thickness of the block varies in discrete steps.

Abstract: A toroidal cavity-type electron accelerator is provided with a pair of electron beam sources. The beams from the two sources are respectively injected into the accelerating cavity at the mid-plane thereof and at a point displaced from the mid-plane whereby the electrons comprising the beam injected on the mid-plane will be accelerated while the electrons comprising the beam injected at the off mid-plane location will be decelerated and contribute their energy to producing a field for accelerating the electrons of the other beam.
