  1. 1st ANL LCLS All Hands Meeting 20 February, 2006

  2. Purpose • Remind you what the project is all about. • Bring you up to date on the overall project status. • Define clearly what ANL/APS is to deliver. • Bring you up to date on the details of where we are at with the delivery of the LCLS undulator system. • Where possible explain the transition from ANL to SLAC. • Give some look ahead about what we need to accomplish in the coming couple of years. • Explain where required how we are managing this.

  17. Magnet Measurement Facility – Ready in March

  18. MMF construction reveals Ladera sandstone

  19. Recent Significant Changes • Diagnostics • Descope • Wires Scanners • Optical transition radiation monitors • Rescope • End-of-undulator diagnostics • Reduced in value and moved to John Arthur’s discretion • Details of what we build still need to be worked out • Anticipate some savings of the Hydrostatic Level System • Scope Added • Beam Finder Wire (33) • Will be used to locate the “loose end” of the undulator • Will also be used as a beam profile monitor • m – metal shields (to be added soon)

  20. Where this Brings Us • Originally • Undulator System TPC ~$55M • Now ~$45M

  21. Significant “Hot Topics” • RF Beam Position Monitors • Essential for effective operations • We must accelerate their development and completion • Single Undulator Test • Essential to test all form and fit • ANL/SLAC Integration • Need to work more closely with SLAC to ensure • Smooth transfer of knowledge and equipment to SLAC • Clean development of assembly and installation plans

  22. 6 Month Look Ahead Plan/Goals • Undulator • First articles assembled, tested, and at least 1 shipped to SLAC • Assembly production begun by both vendors • Single Undulator Test • Completed but still available for testing purposes • Magnet Measurement Facility • Being commissioned • Vacuum System • Main chamber full scale prototype complete • All other major components prototypes near completion • Diagnostics • Injector test stand testing with beam through the rf bpm completed • Installation complete of the three bpm test and testing with beam imminent • Beam loss monitor design and engineering in progress • Testing of beam finder wire prototype completed • End-of-undulator details fully understood and decisions made about scope • Integration, Assembly, and Installation Planning • Refined and ready to proceed

  23. Further Look Ahead • We will be (we better be) delivering loads of undulators, supports, diagnostics, etc. starting very soon and continuing through all of 2007. • It is going to get very busy in the magnet measurement facility. • All initial assembly is done there along with all measurements and fiducialization. • Overall system integration and assembly planning and refinement are crucial. • We will have no time to waste • Installation in the undulator tunnel will begin roughly in June 2007 (15 months away)

  24. Other Comments • It is imperative that we • Work together as a team • Both within ANL and together with SLAC • Don’t reinvent the wheel if it is not needed • Leverage what other people have done • Accept constructive criticism • Communicate • Move quickly and without delay • Don’t let things linger • We want the ANL LCLS project to look like a model of how one effectively accomplishes a project

  25. I’m Almost Done!

  26. LCLS Design Permits Expansion • 2nd undulator accommodated in the LCLS tunnel • Expandable to at least six “hard x-ray” FEL undulators • Without loss of original investment

  27. Looking Ahead – LCLS development Spring-8 European XFEL

  29. Effort Management • Comparison to the ANL system • ANL system uses estimates generated in the middle of the month by each individual • This in turn is compiled by hand by a variety of people from secretaries to division HR • This information is then passes on to the individual division offices, compiled again by hand and then entered into the ANL HR accounting system • The LCLS uses approximately 50 cost codes and 4 ANL Divisions in 2 different ALDships • Needless to say the above method, handled differently by different divisions, different individuals, and different ALDships leads inevitably to errors • We developed our own completely electronic system to provide a cross check to the official ANL system and manage/control our accounting
