  Over the last decades, significant advances in high-power laser systems have
enabled rapid progress in the development of laser-driven plasma accelerators.
Today, the results obtained in beam stability and reproducibility present laser
plasma acceleration as a viable and promising alternative to conventional
accelerators. As several electron beam and secondary sources applications
require high average currents, a major focus is now on increasing the beam's
repetition rate. In the following, we introduce a novel plasma source for kHz
electron acceleration, providing a continuous and spatially confined gas flow,
while minimising the gas load in the acceleration chamber.
