摘要
The divergence of the magnetic field for confining the ionized gas (9) in a sealed high-flux neutron tube comprising a Penning-type ion source (1) is increased in the direction of the ion emission zone by influencing the magnet assembly (8) of the ion source. The ion beam extracted from the plasma is accelerated (2) and projected onto a target (4). The geometry and the position of the anode (13) inside the ion source are adapted to the topography of the lines of force in order to ensure minimum interception of the ionizing electrons moving in the structure, which adaptation is achieved notably by using a truncated anode whose generatrices take the shape of the lines of force.
