LCP injection into vacuum: a frame from a movie taken with the in vacuum camera during measurements at the LCLS. The nozzle shadow is on the right, and the X-ray pulse impact on the LCP jet (arrow) can be seen as a black bubble. LCP is extruded at a flow rate of 300 pl min−1. The pressure on the LCP was 3000 psi. The LCP extrusion speed was so slow that the X-ray pulse repetition rate at the LCLS had to be reduced to 1 Hz. X-ray energy: 9.4 keV, X-ray beam attenuated to 7%. LCP stream diameter: 20 μm.
