Abstract: The invention relates to a charged particle accelerator device including a subharmonic cavity 3 allowing formation of the particles by cluster 60. The subharmonic cavity 3 is arranged between a particle source 2 and an accelerator structure 4 comprising a succession of accelerator cavities (C1,...,Cn). The particle current is modulated in the subharmonic cavity 3 by an electromagnetic wave O2. An entrance plane 30 of the subharmonic cavity 3 and a second entrance plane 31 of a first accelerator cavity C1 are situated at a given distance D from one another, along a longitudinal axis 9 of the accelerator structure 4. According to a characteristic of the invention, the value of the ratio of the said distance D to the wavelength lambda 2 of the electromagnetic wave O2 is less than 0.3.
