In accordance with the invention, on the two above layers there is deposited a stack of active layers (21, 23, 25, 27) which are identical to the layer (19) and which are separated from one another by diffusion barriers (20, 22, 24, 26, respectively). The thickness of each of said active layers is in the order of the penetration depth of the deuterium ions striking the target.Field of SearchIncluding accelerating particles into a stationary or static target (e.g., Cockcroft-Walton generator type)With target replenishing With means for modifying the resultant neutron output, e.g., moderator means With means to pulsate ion beam Self-contained neutron sources (e.g., neutron or accelerator tube) With cooled electrodes or target With ion beam collimator or filtering structure (e.g., extractor electrode) With ion beam collimator or filtering structure Fusion targets or pellets | |
