| TUPSM038 | Status of the Re-Entrant Cavity Beam Position Monitor for the European XFEL Project | 210 |
|
||
The European XFEL is a research facility, currently under construction in Germany. It is based on a superconducting electron linac including about 100 cryomodules based on the TESLA technology. Each cryomodule is equipped with a beam position monitor connected to a quadrupole at the high-energy end of the cavity string. Around one third of cold BPMs will be re-entrant RF cavities. This contribution will describe the present status of the cold re-entrant cavity BPM, and will present measurements of the BPM pickup and electronics prototypes. |
