A full waveform model for arbitrarily axis-symmetric black hole mergers
Song Li, Wen-Biao Han
In this work, we present a non-GR full waveform for general parametrization of axisymmetric black holes by extending our previous PSI model. Our model comprises two main components…
Gravitational waveform model based on photon motion for spinning black holes
Song Li, Wen-Biao Han
The waveforms from binary black hole mergers include inspiral, merger, and ringdown parts. Usually, the inspiral waveform can be obtained by calibrating from post-Newtonian approxi…
Ultra-short, MeV-scale laser-plasma positron source for positron annihilation lifetime spectroscopy
Thomas L. Audet, Aaron Alejo, Luke Calvin +10
Sub-micron defects represent a well-known fundamental problem in manufacturing since they can significantly affect performance and lifetime of virtually any high-value component. P…
Quasi-monoenergetic Electron Beams from Laser-plasma Acceleration by Ionization-induced Injection in Low- density Pure Nitrogen
Mengze Tao, Nasr A. M. Hafz, Song Li +5
We report a laser wakefield acceleration of electron beams up to 130 MeV from laser-driven 4-mm long nitrogen gas jet. By using a moderate laser intensity (3.5*10^18 W.cm^(-2)) and…
Enhanced laser-driven electron beam acceleration due to ionization-induced injection
Song Li, Nasr A. M. Hafz, Mohammed Mirzaie +5
We report an overall enhancement of a laser wakefield acceleration (LWFA) using the ionization injection in a mixture of 0.3 % nitrogen gas in 99.7 % helium gas. Upon the interacti…
Enhanced electron yield from a laser-plasma accelerator using high-Z gas jet targets
Mohammad Mirzaie, Nasr A. M. Hafz, Song Li +5
An investigation of the multi-hundred MeV electron beam yield (charge) form helium, nitrogen, neon and argon gas jet plasmas in a laser-plasma wakefield acceleration experiment was…
Generation of electron beams from a laser-based advanced accelerator at Shanghai Jiao Tong University
Ahmed M. M. Elsied, Nasr A. M. Hafz, Song Li +3
At Shanghai Jiao Tong University, we have established a research laboratory for advanced acceleration research based on high-power lasers and plasma technologies. In a primary expe…
