Impact of Residual Angular Chirp in a Petawatt-class Laser System on Laser-driven Proton Acceleration
Qingfan Wu, Minjian Wu, Jiarui Zhao +25
The paper shows that a small residual angular chirp caused by misaligned grating compressors in a petawatt laser degrades the focal spot and reduces proton energies, and that remov…
HotLoop Optimization of Petawatt Laser Focal Spot via a Twin-Focus Scheme
Qingfan Wu, Ying Gao, Minjian Wu +25
Achieving diffraction-limited focusing of high-power laser pulses to generate ultra-high intensities is crucial for developing compact laser-driven particle accelerators and explor…
A Spatial-Resolved Proton Energy Spectrometer Based on a Scintillation-Fiber Cube
Tan Song, Ying Gao, Di Wang +18
Advanced particle acceleration methods have produced high-peak-current ion beams with broad energy spread and complex spatial distribution. There is an urgent need to develop onlin…
LongCat-Flash-Thinking-2601 Technical Report
Meituan LongCat Team, Anchun Gui, Bei Li +162
We introduce LongCat-Flash-Thinking-2601, a 560-billion-parameter open-source Mixture-of-Experts (MoE) reasoning model with superior agentic reasoning capability. LongCat-Flash-Thi…
EPIPTrack: Rethinking Prompt Modeling with Explicit and Implicit Prompts for Multi-Object Tracking
Yukuan Zhang, Jiarui Zhao, Shangqing Nie +2
Multimodal semantic cues, such as textual descriptions, have shown strong potential in enhancing target perception for tracking. However, existing methods rely on static textual de…
