Here, we experimentally demonstrate OAM-driven laser wakefield acceleration, producing electron beams with a two-beamlet structure that indicates unique azimuthal dynamics inside the plasma wake. Particle-in-cell simulations reproduced the observed spectral features and revealed helical electron trajectories driven by OAM-pulse-driven wakefields. These results show that the laser driver's phase structure can shape electron acceleration dynamics, opening a route to optimal control of beam structure in compact laser-driven accelerators.
