Polarization-resolved attosecond gamma-ray emission from few-cycle laser interactions with cone targets
De-Sheng Zhang, Cui-Wen Zhang, Xue-Ren Hong +3
Linearly polarized attosecond -ray pulses in the MeV range are generated from a cone target irradiated by a single few-cycle laser pulse. Electron layers are periodically extrac…
Nonlinear polarization effects on plasma screening for thermonuclear reactions
Hanxiang Huang, Binbing Wu, Zhengfeng Fan +3
We investigate two-center plasma screening effects on thermonuclear reactions of D-T, p-B, and C-C, spanning from classical to degenerate regimes. The two-cent…
Neutron-source fidelity for laser-driven D--D lithium-blanket tritium-breeding tests
Chengqi-Zhang, Yang He, Mamat Ali Bake +1
The paper evaluates how the actual energy and angular distribution of neutrons from compact laser‑driven D‑D sources influences tritium production in lithium blankets, using partic…
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 (…
A Surrogate Model for Proton Spectrum Prediction to Map Transitions in Laser-Ion Acceleration
Chengqi-Zhang, Yang He, Mamat Ali Bake +2
We present a physics-guided, decoupled dual-branch surrogate model to predict continuous proton energy spectra from laser-driven ion acceleration. Integrating a -VAE for spectr…
