Figure 1
Photon intensity of BL-13A in the photon-energy region between 50 and 2000 eV after installing the APPLE-II EPU. The photon intensities were converted to equivalent values for a ring current of 450 mA. The VLSGs with line densities of 300 and 1000 lines mm−1 cover photon energies between 48 and 300 eV and between 100 and 2000 eV, respectively. The photon intensity variation before the insertion-device upgrade is shown by dotted lines. The exit-slit width was 100 µm. |
