Operation of the XFEL Accelerator

OPs-5xx: Infrastructure


OP-510: Technical Infrastructure

The tasks of OP-510 are concerned with the operation, maintenance and repair of power, water, an dair systems of the technical infrastructure as needed for the accelerator operation. It comprises equipment installed in the buildings XHVAC, XHPSC, XHEIN, XSIN, XTIN, XHM, XHEE, XSE, XTL, XHE1-4, XS1-4, XTD1-10 (except for special undulator temperature stabilization systems), XSDU1-2, AMTF and the cryogenics hall (XHC). The basic utility equipment in the experiment hall XHEXP1 is included here, but not special equipment in the experiment areas.
In the operation phase, the tasks of OP-510 include the operation, repair and maintenance of the following sub-systems in the tunnels and buildings listed above:


OP-515: Transport & Alignment


OP-520: IT & Networks (for accelerator operation)


OP-525: Asset Management

During the construction of the European XFEL, detailed technical as-built documentation has been generated for the accelerator. It is based on a configuration database (the DESY EDMS), which provides an inventory of major accelerator systems. The configuration database registers components and their used materials and tracks component design and fabrication history. It contains documents such as specifications, 3D-CAD models and drawings, work instructions, inspection and repair records, certificates and more. The EDMS offers many reports which were customized for the XFEL during the construction project.
The documents, records and reports are of great importance for maintaining the accelerator throughout its life-time. They can be accessed online by the service crews in the tunnel during access for maintenance and repairs.


OP-530: AMTF

The AMTF (Accelerator Module Test Facility) was build during the XFEL construction to test and qualify all SC cavities and the fully assembled accelerator modules. The hall also houses the Waveguide Assembly and Test Facility (WATF). The AMTF is a major asset for the XFEL operation and future development. Its cryogenic installation can be used as a back-up to keep the XFEL linac cold (only without RF operation).
OP-530 operates, maintains and (if needed) upgrades the installation for cavities and module tests in the AMTF. The WATF is part of OP-210
