We demonstrate laser-driven acceleration of electrons to MeV-scale energies at 1 kHz repetition rate using pulses focused on near-critical density He and gas jets. Using the gas jet, electron acceleration to in bunches was observed with laser pulse energy as low as 1.3 mJ. Increasing the pulse energy to 10 mJ, we measure charge bunches with energy for both He and gas jets.
