Figure 3
Side view images (10× magnification, NA 0.28, 1075 × 310 pixels2 detection area, pixel size ∼0.65 µm) taken inside the SPB/SFX sample chamber, each depicting a thin liquid jet (water) generated by a 75–60–75 (µm) GDVN using a liquid flow rate of Ql = 10 µl min−1 and an applied gas pressure of pHe = 400 psi (Qg = 25 mg min−1). (a) The liquid jet in the absence of X-rays. (b) X-ray pulses arrive at f = 0.564 MHz (with 30 pulses per train) and create gaps in the liquid column (gap-to-gap spacing Δx = 104.7 µm). The X-ray interaction with the jet hence reveals a jet velocity of vjet = Δx × fpulse = 59.1 m s−1. (c) Two optical lasers (λ = 532 nm), each with a 5 ns pulse duration, illuminate the droplets 2 mm downstream of the jet region. The delay time between the two laser pulses is 119 ns and reveals a droplet displacement of Δx = 7.2 µm. Therefore, dual-pulse laser illumination reveals a droplet velocity of vdroplet = Δx/Δtopt.pulse = 60.1 m s−1. The determined jet velocities imply a jet diameter of djet = [4Ql/(πv)]1/2 ≃ 2 µm. |
