Beam Diagnostics for PAL-XFEL | |
|
||
| Pohang Accelerator Laboratory started its XFEL program from 2011. The XFEL project in Pohang Accelerator Laboratory (PAL) requires low beam-emittance, ultra-short bunch length, high peak current, high stability of beam energy. Therefore, beam diagnostics for SASE XFEL should be, focused on attaining femto-second precision in the measurement of temporal beam parameters, and sub-micrometer precision in beam position measurement. Charge measurement and energy measurement and their feedback are important as well. In this work, technical concepts regarding the diagnostic monitors will be summarized and present status of them will be described. | ||

Beam Diagnostics of Injector Test Facility for PAL XFEL | |

Funding: Supported by the Ministry of Education, Science and Technology in Korea. We are constructing an injector test facility (ITF) for the PAL XFEL. The target of the facility is to demonstrate an emittance of < 0.5 mm mrad (projected, normalized rms) at the beam charge of 200 pC with small energy spread and high stablities. By collaborating with the RADIABEAM Technologies*, we have developed beam diagnostics with enough precision and reliability to provide beam information including beam energy, energy spread, charge, profile, position, and bunch length. Resolutions of the beam-size and position measurements will be 17.5 um (rms, for OTR screens) and < 10 um (rms) respectively. A S-band transverse deflecting cavity will be used for measuring the bunch length with resolution down to 10 fs. In this article we report on current status of the PAL-XFEL injector test facility with emphases on its beam diagnostics. * http://www.radiabeam.com/ |
