Abstract Laser Inertial Fusion Energy reactor requires repetitive fuel pellet injection and laser engagement to fuse fusion fuel beyond a few Hz. We demonstrate 10 Hz free-fall bead pellets injection and laser engagement with γ-ray generation. Diameter of 1 mm deuterated polystyrene beads were engaged by counter illuminating ultra-intense laser pulses with intensity of 5 x1017 W/cm2 at 10 Hz. The spatial distribution of free-fall beads was 0.86 mm in horizontal, and 0.18 mm in vertical. The system operated beyond 5 minute, 3500 beads supply with achieved frequencies of 2.1 Hz for illumination on bead and 0.7 Hz for γ-ray generation, these frequencies increments three times in relation to the previous 1 Hz injection system. The operation duration was limited by pellet supply. This injection and engagement system can apply for Laser Inertial Fusion Energy research platform.
