    A beam of relativistic charged particles, when entering the plasma, experiences beam-plasma instability. If the beam is long enough, longer than the plasma wavelength, it divides into a train of microbunches, namely, it self-modulates. This process is highly nonlinear, but under certain conditions becomes reproducible. The way the beam self-modulates depends on the parameters of the system,...

  80. 18. Investigation of electron beam properties from few-TW LWFA using an N₂–He gas mixture with variable nitrogen doping in a gas cell
    MING-WEI LIN (National Tsing Hua University)
    19/06/2025, 15:50

    Focusing few-TW or even sub-TW laser pulses into a sub-mm-long, dense gas cell opens up opportunities for realizing laser wakefield acceleration of electrons with 100-nA-level currents driven by modern high-repetition-rate lasers. Although the use of pure nitrogen in the cell facilitates the routine generation of 10-MeV-scale electron beams, the strong ionization of nitrogen ions toward higher...

    Continuous Integration/Continuous Delivery (CI/CD) can facilitate the development and integration process of advanced photon source software and algorithms. A significant amount of repetitive tasks, such as compiling, testing, deploying, and releasing, may impede the progress of algorithm and software development. Developers often need to expend considerable effort maintaining servers and...

  84. 27. All-Optical Blast-Wave Control of Laser Wakefield Acceleration in a Near-Critical Plasma
    Ivan Tsymbalov (Institute for Nuclear Research of Russian Academy of Sciences)
    19/06/2025, 16:10

    We propose a novel method for changing the length of laser wakefield electron acceleration in a gas jet using a cylindrical blast-wave created by a perpendicularly focused nanosecond laser pulse. The shock front modifies the wake significantly and stops interaction between the laser pulse and accelerated electron bunch, allowing one to directly control the interaction length and avoid...
