“…By bombarding secondary targets (e.g. blocks of lithium, Beryllium or deuterated plastic) using the ions, nuclear reactions are triggered, producing high fluxes of beamed neutrons with multi-MeV energies [18][19][20][21][22][23].…”

The continued improvement of high power laser technologies is recasting the prospects of smallscale neutron sources, to enable scientific communities and industries performing experiments that are currently offered at extensive accelerator-driven facilities. This paper reports moderation of laser-driven fast neutrons to thermal energies using a compact, modular moderator assembly. A significant thermal (∼ 25 meV) flux of ∼ 10 6 n/sr/pulse was measured from water and plastic moderators in a proof-of-principle experiment employing a relatively moderate power laser delivering 200 J on target in 10 ps. Using MCNPX simulations, the experimental results are reproduced and discussed.

“…Los Alamos National Laboratory (LANL) and collaborators have pioneered a novel, short duration yet extremely intense neutron source using the short-pulse laser at LANL's TRIDENT laser facility [5][6][7][8][9]. The TRIDENT laser facility was, until it's closure in 2016, one of the most intense and powerful short-pulse lasers in the world, providing a very high contrast laser pulse of ~600 fs in duration, ~80 J energy, and with a wavelength of 1053 nm.…”

“…Concepts and efforts for laser deuteron catcher target systems were summarized in a report by our team [7], including a discussion of alternative solutions for the solid targets, left with a hole after each laser shot, such as gas or liquid cryo-jet target systems. Our team collaborates with laser facilities and will utilize them to produce neutrons as they become available after required upgrades, e.g.…”

Neutron production with laser-driven neutron sources was demonstrated. We outline the basics of laser-driven neutron sources, highlight some fundamental advantages, and quantitatively compare the neutron production at the TRIDENT laser sources with the well-established LANSCE pulsed neutron spallation source. Ongoing efforts by our team to continue development of these sources, in particular the LANSCE-ina-box instrument, are described. The promise of ultra-intense lasers as drivers for brilliant, compact, and highly efficient particle accelerators portends driving next-generation neutron sources, potentially replacing in some cases much larger conventional accelerators.
