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. | ||

|
||
| This paper presents an overview of the magnet power supply(MPS) for the PAL-XFEL. The number of total MPS is 628 and they will be installed along the accelerator and the undulator sections. The power capacity of the MPS was ranging from about 1 A to 300 A. These MPSs were required to meet the high stability that was subjected from the beam dynamics specifications. This paper described the overall MPS requirements, MPS assembling, test process, control scheme, installation plan and so on. | ||
| MOP033 | Design, Fabrication, and Performance Tests of Dipole and Quadrupole Magnets for PAL-XFEL | 90 |
|
||
| PAL-XFEL is now being constructed in Pohang, Korea. This facility will consist of a 10 GeV linac and five undulator beamlines. As the first phase we will construct one hard X-ray and one soft X-ray beamlines which require 7 different families of dipole magnets, and 11 families of quadrupole magnets. We are designing these magnets with considering the efficient manufacturing and the proper power supplies. In this presentation, we describe the design features of the magnets, the manufacturing, and the thermal analysis with the test results. | ||
