- 摘要：
- The neutrons with desired parameters can be obtained after initial neutrons penetrating
various structure and component of the material. A novel method, the
“neutron channel design”, is proposed in this investigation for gaining the desired
neutrons. It is established by employing genetic algorithm (GA) combining with
Monte Carlo software. This method is verified by obtaining 0.01eV to 1.0eV neutrons
from the Compact Accelerator-driven Neutron Source (CANS). One layer
polyethylene (PE) moderator was designed and installed behind the beryllium target
in CANS. The simulations and the experiment for detection the neutrons were
carried out. The neutron spectrum at 500cm from the PE moderator was simulated
by MCNP and PHITS software. The counts of 0.01eV to 1.0eV neutrons were simulated
by MCNP and detected by the thermal neutron detector in the experiment.
These data were compared and analyzed. Then this method is researched on designing
the complex structure of PE and the composite material consisting of PE, lead
and zirconium dioxide. © 2016 Author(s). All article content, except where otherwise
