Progress of the PAL-XFEL Undulator System | |
|
||
Pohang Accelerator Laboratory (PAL) is developing 10 GeV, 0.1 nm SASE based FEL for high power, short pulse X-ray coherent photon sources named PAL-XFEL. At the first stage PAL-XFEL needs two undulator lines for photon source. PAL is developing undulator magnetic structure based on EU-XFEL design. For hard X-ray lines, we need 18 26.0 mm period hybrid type planar undulator structures, and for soft X-ray lines, 6 planar undulator with 37 mm period is planned with a couple of EPUs for polarization control. In this report we summarize the progress in the undulator system. Particular emphasis will be the results of the local-K correction, which is essential to speed-up the pole tuning process. | ||
