Abstract
To greatly enhance output of fusion-produced neutrons in a laser-initiated Coulomb explosion (CE) of D clusters, we propose to accelerate D+ ions by an electrical pulse to the energies where the collision cross-section is the highest. With ions bombarding a D-rich cathode, this solves a few problems simultaneously by (a) removing the electron cloud hindering the CE, (b) utilizing up to 100% of the ions to hit the high-density packed nuclei, and (c) reaching the highly increased cross-section of neutron production in a single collision, by using a multi-layered target. We show that neutron output can reach up to 1015 per shot, which provides a powerful and compact neutron source. We also consider the use of E-pulse acceleration for diagnostic purposes.
