STUDIES ON TRANSPORTATION OF SUPERCONDUCTING RESONATORS AND BEAM POSITION MONITOR - QUADRUPOL UNITS FOR THE XFEL PROJECT

For the XFEL project industrial companies in Germany and Italy are in charge of the cavity fabrication and preparation. For the radio frequency acceptance test these cavities have to be transported to the DESY site in Hamburg without losing the performance. The XFEL Beam Position Monitor and Quadrupol Units (BQU) are completed in the DESY clean room. The cavities and the BQU are handed out in the status “ready for assembly” to the string assembly site at CEA Saclay in France. These components have to be transported without risk of damages or reduction of performance. To ensure that the transports over European routes do not influence the performance of cavities or are origin of particulates inside the BQU, individual transport boxes for super conduction cavities and transport fixtures for the BQU are designed and tested.
