Neutron-source fidelity for laser-driven D--D lithium-blanket tritium-breeding tests
Chengqi-Zhang, Yang He, Mamat Ali Bake +1
Compact deuterium--deuterium (D--D) neutron sources can provide controllable irradiation fields for lithium-blanket studies, although their broad joint energy and angle distributio…
Multi-objective Bayesian optimisation of a double-layer target for quasi-monoenergetic TNSA protons
Chengqi-Zhang, Yang He, Mamat Ali Bake +1
We carry out a six-parameter multi-objective Bayesian optimisation of a carbon--hydrogen double-layer target for target-normal-sheath proton acceleration. The campaign consists of…
Bayesian optimization of double-pulse temporal shaping for enhanced target-normal-sheath proton acceleration under fixed laser energy
Chengqi-Zhang, Yang He, Mamat Ali Bake +1
Splitting an ultrashort drive pulse into a weak leading pulse and a strong main pulse is known to raise the energy of protons accelerated by the target-normal-sheath-acceleration (…
Enhancement of Proton Acceleration via Geometric Confinement in Near Critical Density-filled Targets
Cheng-Qi Zhang, Yang He, Mamat Ali Bake +1
High-quality proton beams generated by laser-plasma interactions are of significant interest for applications ranging from tumor therapy to fast ignition in inertial confinement fu…
