Description

The NanoPlasmonic Laser Induced Fusion Energy (NAPLIFE) project by simultaneous ignition of the whole target, aims to avoid instabilities and pre-detonation. Fusion by regulating the laser light absorption via resonant nanorod antennas implanted into hydrogen rich polymer targets. This is the only project using this method, up to now. Boron-nitride (BN) was added to UDMA-TEGDMA polymer. Theoretical considerations and first verification experiments are presented. Our experiments with resonant nanoantennas accelerated protons up to 225 keV energy were accelerated. These protons led to p + 11B fusion, indicated by the sharp drop of observed backward proton emission numbers at the 150 keV resonance energy of the reaction. The generation of alpha particles was verified.
