  1. 90. High-efficiency and high-quality laser-plasma accelerator stages for a plasma-based linear collider
    Carlo Benedetti (LBNL)

    WG1 Oral: Laser-Plasma Wakefield Acceleration
    Contributed Oral

    The viability of next generation plasma-based linear colliders relies on the possibility of accelerating high-charge and low-emittance bunches to high energies over short distances with high efficiency, while keeping a small relative energy spread. Laser-plasma accelerators (LPAs) can operate in different regimes, namely, linear (or mildly nonlinear) stages, where laser guiding is achieved by...

  2. 115. Spatial temporal couplings and the generation of Stimulated Raman Side Scattering
    Alexander Sävert (Helmholtz Institute Jena)

    WG1 Oral: Laser-Plasma Wakefield Acceleration
    Contributed Oral

    We report on experiments investigating the influence of spatio-temporal couplings (STCs) in the laser focus on stimulated Raman Side Scattering. We find a discrepancy between measured scattered angles and classical theory. At the same time, the angle changes with propagation of the driving laser pulse. This mismatch can be resolved if the pulse front tilt (PFT) of the laser pulse is taken into...

  3. 120. The BELLA PW iP2&2BL Upgrades – Radiation and Laser Safety considerations and implementations for safe and efficient user experiments
    Csaba Toth (Lawrence Berkeley National Laboratory)
    11/9/22, 2:10 PM
    WG8 Oral: Advanced Laser and Beam Technology and Facilities
    Contributed Oral

    After a decade-long successful operations [1] and producing new results in the field of Laser Plasma Acceleration (LPA) research [2-4] by the Berkeley Lab Laser Accelerator (BELLA), the PW laser system’s recent upgrades were completed in 2022. The first is the “Second Beamline” (PW-2BL), where the fully amplified, stretched pulses are split before compression, enabling two independently...

  4. 158. Updates and Commissioning results of the Second Beamline Upgrade to BELLA PW
    Alex Picksley (Lawrence Berkeley National Laboratory)
    11/9/22, 2:30 PM
    WG1 Oral: Laser-Plasma Wakefield Acceleration
    Contributed Oral

    The petawatt (PW) facility at Berkeley Lab Laser Accelerator (BELLA Center) has successfully performed several experiments since its installation in 2012 [1], primarily focusing on optimization of single stage, high energy gain laser-plasma accelerators (LPAs) [2,3]. Recently, the facility has undergone two significant upgrades: i) a new second beamline (2BL) delivered into the existing...
