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…
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…
Spin effect in vacuum pair production under two-color rotating electric fields
Zhao-Yuan Chen, Orkash Amat, Jin-hui Bai +1
We investigated the spin effect on the vacuum pair production by Dirac-Heisenberg-Wigner (DHW) formalism under two-color counter-rotating electric fields. We primarily studied the…
