Hard X-ray sources from femtosecond (fs) laser-produced plasmas, including the betatron X-rays laser wakefield-accelerated electrons, have compact sizes, fs pulse duration and pump-probe capability, making it promising for wide use in material biological sciences. Currently main problem with such is limited average flux even ultra-intense pulses. Here, we report ultra-bright can be generated using a clustering gas jet target irradiated small size laser, where ten-fold enhancement of yield...
Following the discovery of Higgs boson at LHC, new large colliders are being studied by international high-energy community to explore physics in detail and beyond Standard Model. In China, a two-stage circular collider project CEPC-SPPC is proposed, with first stage CEPC (Circular Electron Positron Collier, so-called factory) focused on physics, second SPPC (Super Proton-Proton Collider) This paper discusses this stage.
Plasma wakefield acceleration in the blowout regime is particularly promising for high-energy of electron beams because its potential to simultaneously provide large gradients and high energy transfer efficiency while maintaining excellent beam quality. However, no equivalent positron plasma wakes has been discovered date. We show that after a short propagation distance, an asymmetric drives stable hollow channel can be both accelerating focusing beam. A charge bunch placed at suitable...
In recent years, the field of positron acceleration in plasma wakefield accelerators has witnessed rapid theoretical advancements, and several effective schemes have been proposed. these studies, longitudinally uniform is taken into account, with beam located at start second bubble. The electron filament near provides Coulomb attraction force for guiding beam. However, influence vacuum-plasma transition on beams not considered yet, where bubble larger than that density plateau region,...
A novel scheme for the focusing of high-energy leptons in future linear colliders was proposed 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This has many advantageous properties over previously studied schemes, including being significantly shorter a given energy having better bandwidth. Experimental results from ATF2 accelerator at KEK are presented that validate operating principle such by demonstrating demagnification 1.3 GeV electron beam down to below 65 nm height...
Pedestrian protection system plays an important role in perceptual of unmanned vehicles and Advanced Drive Assistant System.

Abstract High-cadence, multiwavelength observations have continuously revealed the diversity of tidal disruption events (TDEs), thus greatly advancing our knowledge and understanding TDEs. In this work, we conducted an intensive optical-UV X-ray follow-up campaign TDE AT 2023lli found a remarkable month-long bump in its UV/optical light curve nearly 2 months prior to maximum brightness. The represents longest separation time from main peak among known TDEs date. outburst declines as t −4.10...
Source optimization (SO) has emerged as a key technique for improving lithographic imaging over range of process variations. Current SO approaches are pixel-based, where the source pattern is designed by solving quadratic problem using gradient-based algorithms or linear programming problem. Most these methods, however, either computational intensive result in window (PW) that may be further extended. This paper applies rich theory compressive sensing (CS) to develop an efficient and robust...
Accurate rainfall-runoff modeling is crucial for disaster prevention, mitigation, and water resource management.
