Publikováno v: Physical Review Accelerators and Beams, Vol 25, Iss 1, p 011301 (2022)

We demonstrate experimentally that hydrodynamic optical-field-ionized (HOFI) plasma channels can be generated at kHz-scale pulse repetition rates, in a static gas cell and for an extended period. Using a pump-probe arrangement, we show via transverse
