Table 5 Experimental jetting parameters set at the SPB/SFX interaction region upstream (IRU) sample chamber (p\(\approx\)\(10^{-3}\) mbar), X-ray parameters and jet characterization results. The ’effective pulse energy’ considers the measured pulse energy at the XTD2 X-ray gas monitor, the selected attenuators at the XTD9 tunnel (total transmission) and that the transmission with the nano-KB mirrors is about 60%. The results from the ’scaling law’ are obtained by applying the jet velocity prediction formula from2. Jets with velocities of v\(\ge\)25 m/s are fast enough for 0.564 MHz operation, while 1.13 MHz operation is compatible with jets with v\(\ge\)45 m/s.
