内容記述 |
Neutron beam is a powerful tool for investigating the structure and properties
of materials used in science and technology. Recently, laser-driven neutron
source (LDNS) is attracting interest because of its small source size,
short and bright pulse of neutrons. LDNSs are getting maturity for several
applications including neutron spectroscopy ever proposed. However,
elucidating the laser-driven ion acceleration mechanism appropriate for neutron
generation and establishing the scaling law on the neutron yield are essential
to improve the feasibility of LDNS. Here we show that the neutron yield increases
with the fourth power of the laser intensity. By installing a moderator, it is demonstrated that the efficient generation of epithermal neutrons enables a single-shot analysis of composite materials by Neutron Resonance Transmission Analysis. This leads to a high-speed analysis of elements and isotopes within sub-μs time and allows its broad applications including non-destructive inspection on site. |
