High-resolution electron microscopy (HREM) and ultrafast electron diffraction (UED) are crucial techniques in material science, biology, and chemistry. They enable researchers to visualize atomic structures and observe fastchanging processes, such as phase transitions, changes in molecular shapes, and chemical reactions, with high spatial and temporal accuracy. However, current electron...
Plasma-based accelerators achieve accelerating fields of 10-100 GV/m. While plasma wakefields naturally accelerate electrons due to their near-light-speed motion [1,2], heavier particles like muons [3] and pions, with lifetimes from microseconds to nanoseconds, struggle to be trapped due to velocity mismatch with the wake.
We use spatio-temporal spectral shaping [4,5,6] to control the group...
The interaction of relativistic particle beams with plasmas underpins a broad range of physical systems — from the dynamics of AGN jets and Gamma-Ray Bursts to next-generation plasma-based accelerators. In both astrophysical and laboratory scenarios, these beam-driven plasma instabilities play an important role on the interplay of kinetic and electromagnetic energy. Understanding the growth...
