|
||
| Pohang Accelerator Laboratory (PAL) is planning to develop a 0.1 nm SASE based FEL as a next generation light source. It will be based on the 10 GeV S-band linac with In Vacuum Undulator system. The proposed in vacuum undulator has 22.3 mm magnetic period with 5.0 mm vertical clearance aperture. The magnetic length will be 4014 mm with breaks between undulators for diagnostic and focusing elements. The mechanical and magnetic requirements of the IVUN system are very challenging. In this report, the design issues related to the development of the IVUN with preliminary magnetic design will be presented. |
