Photon beamline instrumentation & undulators: Session-11
- Jan Grünert (European XFEL GmbH)
Superconducting undulators (SCUs) have been and are successfully delivering x-rays in storage rings. Within its facility development strategy, European XFEL plans to implement SCUs in the upcoming years. This contribution describes different activities ongoing and planned supporting this upgrade.
There are commercially available diamond sensors for synchrotron beams, but they are incompatible for application at XFELs. EuXFEL had launched dedicated R&D to create sensors that survive intense MHz-rate beams and deliver fast pulse-resolved position and intensity data. This presentation reports on new sensors and results of their testing with hard x-ray FEL beam, where we introduced fast...
Variable gap undulators require large and complex motion systems to operate, making their tunability to generate specific radiation wavelengths cumbersome, limited, and slow. RadiaBeam Technologies is engaging in a project to advance undulator manufacturing by utilizing force-neutral adjustable phase undulator (FNAPU) technology developed by Argonne National Laboratory (ANL). This innovative...
The recent LCLS-II upgrade allows operation with bunch rates up to 1MHz for photon energies ranging from 200eV up to about 5keV. The LCLS-II-HE design will extend the high rate capability to 12keV and beyond from an 8GeV superconducting RF linac. The high energy upgrade imposes technical challenges on the X-Ray photon transport line devices to effectively deliver high average power beams to...
