abstract = {Neutrons are a unique tool to alter and diagnose material
properties and excite nuclear reactions with a large field
of applications. It has been stated over the last years,
that there is a growing need for intense, pulsed neutron
sources, either fast or moderated neutrons for the
scientific community. Accelerator based spallation sources
provide unprecedented neutron fluxes, but could be
complemented by novel sources with higher peak brightness
that are more compact. Lasers offer the prospect of
generating a very compact neutron source of high peak
brightness that could be linked to other facilities more
easily.We present experimental results on the first short
pulse laser driven neutron source powerful enough for
applications in radiography. For the first time an
acceleration mechanism (BOA) based on the concept of
relativistic transparency has been used to generate
neutrons. This mechanism not only provides much higher
particle energies, but also accelerated the entire target
volume, thereby circumventing the need for complicated
target treatment and no longer limited to protons as an
intense ion source. As a consequence we have demonstrated a
new record in laser-neutron production, not only in numbers,
but also in energy and directionality based on an intense
deuteron beam. The beam contained, for the first time,
neutrons with energies in excess of 100 MeV and showed
pronounced directionality, which makes then extremely useful
for a variety of applications.The results also address a
larger community as it paves the way to use short pulse
lasers as a neutron source. They can open up neutron
research to a broad academic community including material
science, biology, medicine and high energy density physics
as laser systems become more easily available to
universities and therefore can complement large scale
facilities like reactors or particle accelerators. We
believe that this has the potential to increase the user
community for neutron research largely.},
