Studies on Optimization of Solid W-Target in Accelerator-Driven System

  • The geometry of the solid target for the accelerator-driven system was optimized. The yield and spectrum of leaked neutrons, and the energy deposition in the target were studied. A target assembly consisting of tungsten diskes and water layers was proposed in the present work. The problem of large energy deposition in soild target was solved without decreasing the leakage neutron production.

Abstract: The geometry of the solid target for the accelerator-driven system was optimized. The yield and spectrum of leaked neutrons, and the energy deposition in the target were studied. A target assembly consisting of tungsten diskes and water layers was proposed in the present work. The problem of large energy deposition in soild target was solved without decreasing the leakage neutron production.
