    Abstract: The bunching device in accordance with the invention is essentially constituted by a cylindrical cavity resonator, which advantageously replaces the conventional device encountered in linear accelerators, including a velocity-modulation cavity for modulating the particles and a drift space for bunching said particles. The length of this bunching cavity is associated with the velocity of the particles in said cavity and with the operating frequency of the accelerator. A device of this kind, which is of small size and low cost, renders unnecessary the conventional control of amplitude and phase of the signals which are injected into the bunching device and the accelerator structure, which are coupled in a direct manner. Furthermore, it enables operation to be carried out under conditions of heavy current, whilst achieving good efficiency.

    Abstract: The invention relates to an arrangement for accelerating, to a predetermined velocity at least one bunch from a bunched beam of particles, the length of said bunch corresponding to one cycle of the high frequency of the accelerator. In this arrangement the injection voltage V of the beam is raised to a value larger than the cut-off voltage Vc of the accelerator, exclusively during a short period. Said injection voltage V is created by the addition of a pulsed voltage Vo and high-frequency voltages V1 and V2 generated in resonant cavities 3 and 4 disposed in the trajectory of the beam and tuned respectively to a sub-multiple of said high frequency.
