A new tri-particle backlighter for high-energy-density plasmas (invited).

A new tri-particle mono-energetic backlighter based on laser-driven implosions of DTHe gas-filled capsules has been implemented at the OMEGA laser. This platform, an extension of the original DHe backlighter platform, generates 9.5 MeV deuterons from the THe reaction in addition to 14.

The conceptual design of 1-ps time resolution neutron detector for fusion reaction history measurement at OMEGA and the National Ignition Facility.

The nuclear burn history provides critical information about the dynamics of the hot-spot formation and high-density fuel-shell assembly of an Inertial Confinement Fusion (ICF) implosion, as well as information on the impact of alpha heating, and a multitude of implosion failure mechanisms. Having this information is critical for assessing the energy-confinement time τE and performance of an implosion. As the confinement time of an ICF implosion is a few tens of picoseconds, less than 10-ps time resolution is required for an accurate measurement of the nuclear burn history.
