The European X-Ray Laser Project XFEL tuner Plans

The European X-Ray Laser Project XFEL tuner: Plans for the integration into the Accelerator Modules Lutz Lilje, DESY for the XFEL tuner team Lutz Lilje, DESY CEA Saclay, May 2008 XFEL X-Ray Free-Electron Laser

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Outline Piezo System – Plan for • Quality control (QC) • Installation procedure – Tests at Saclay Mechanics Drive Unit ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 2

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Plan for Quality Control – All components should have documentation of the companies delivered with them • Certificate of conformance – Includes • Dimensional checks • Functional check – Few additional checks at Saclay ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 3

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Mechanics – Delivered as • Clean – Will specify ultrasound + drying – oilfree seems to be to vague • Bagged • Humidity sensor? • Certificate of conformance, documentation Mechanics – QC at Saclay • Check integrity of bag and humidity • Check documentation Tuner Ring – Tuner ring on cavity? ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 4

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Drive Unit – Delivered as • Cold test at liquid N 2 at company • Clean • Double Bagged • Humidity sensor • Certificate of conformance, documentation of tests etc. Drive Unit – QC at Saclay • Check integrity of bag and humidity • Check documentation – Mounting is part of the module assembly – Test drive after tuner assembly and after module assembly ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 5

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Piezo System – Delivered as Piezo System • 2 Piezos – With cables sufficient for connect to flange at coupler – Clean – Bagged – Humidity sensor? – Certificate of conformance » Need functional test ? – Piezo Fixture as part of the mechanics package – Mounting is part of the module assembly ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 6

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Summary: Assembly steps at CEA – Piezo fixture completion • Mount 2 Piezos into fixture with correct pre-load – Assembly of mechanics and drive unit to string • Test drive – Cabling in module • Connect piezo to feedthrough at coupler flange • Connect motor to harness – Installation into cryostat • Test drive ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 7

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Open Points – Cable harness for motors • Delivery by WP 03 or WP 07? – Currently in WP 03 – Piezo system • Connection to flange – soldered (preferred) or connector • To be defined – Detailed completion of the piezo fixture – Simple functional test (at company and) at Saclay – Milestones • Should be defined by start of module assembly plus safety margin • Need storage for 32 systems – 1 month of production ﴀ Lilje, DESY Lutz CEA Saclay, May 2008 8
