Figure 2
XFEL pulse energies of the three beamlines: (a) BL1, (b) BL2 and (c) BL3. Red dots represent single-shot results and black lines indicate averaged values over 1 s. The pulse energies of BL1 were measured after the beamline slit, and those of BL2 and BL3 were measured during the multiple-beamline operation. The electron beam energies and K values were 0.78 GeV and 2.1 for BL1, 6.5 GeV and 2.6 for BL2, and 7.8 GeV and 2.1 for BL3. The laser pulse frequencies were 60 Hz for BL1 and 30 Hz for BL2 and BL3. |
