    WG7 Oral: Radiation Generation and Advanced Concepts
    Contributed Oral

    Relativistic streaming plasma instabilities and their growth rates are subject of research for the description of jet-like astrophysical plasmas due to their strong influence on energy transfer between plasma-constituent, electromagnetic fields and photons. Therefore, these instabilities are of relevance in the description of highly energetic astrophysical phenomena such as e.g. the formation...

    WG7 Oral: Radiation Generation and Advanced Concepts
    Contributed Oral

    The upgraded Facility for Advanced Accelerator Experimental Tests (FACET-II) at SLAC has started delivering the first electron beams for the initial phase of several experimental campaigns hosted at the facility. During these first runs, the users have been able to test and commission different elements of their set-up, but also to obtain preliminary data to characterise the experimental...

  3. 130. Positron Driven High-Field Terahertz Waves via Dielectric Wakefield Interaction
    Nathan Majernik
    11/9/22, 2:10 PM
    WG4 Oral: Beam-Driven Acceleration
    Contributed Oral

    Advanced acceleration methods based on wakefields generated by high energy electron bunches passing through dielectric-based structures have demonstrated >GV/m fields, paving the first steps on a path to applications such as future compact linear colliders. For a collider scenario, it is desirable that, in contrast to plasmas, wakefields in dielectrics do not behave differently for positron...

  4. 150. First results from the E332 Experiment Studying the Near-Field-CTR-based Self-Focusing Effect with High Intensity Electron Beams at FACET-II
    Doug Storey (SLAC National Accelerator Laboratory)
    11/9/22, 2:30 PM
    WG4 Oral: Beam-Driven Acceleration
    Contributed Oral

    The Near-Field Coherent Transition Radiation (NF-CTR) generated in the passage of an intense, highly compressed electron beam through a foil produces surface fields that can provide a strong self-focusing force back on the beam itself, and the intense emission of gamma-rays by the beam. This self-focusing effect can be enhanced by passing the beam through multiple foils of order micrometer...
