  1. Undulator Vacuum System/Mechanical By Dean R Walters Advanced Photon Source Argonne National Laboratory

  2. Undulator Vacuum System/Mechanical • Talk Outline • Undulator Chamber & Bellows • Vacuum System • Beamline Diagnostics • Schedule Highlights

  3. Undulator Vacuum System • Undulator Chamber & Bellows • Chamber Design • Bellows Design • Status of the Prototype

  4. Undulator Vacuum Chamber with Supports Undulator Moves In & Out Vacuum Chamber & Bellows • Design

  5. Chamber Strongback Tubular Chamber 6 mm OD X 5 mm ID Supports Vacuum Chamber & Bellows • Prototype Design

  6. Vacuum Chamber & Bellows Chamber Drawings

  7. Vacuum Chamber & Bellows Bellows Design Drawn by SH Lee

  8. Vacuum Chamber & Bellows Bellows Design (Expanded View) Drawn by SH Lee

  9. Undulator Vacuum Chamber • Status of Prototype • Chamber • Drawings Complete • Outside shops have completed all quotations • All orders have been issued • ANL shop work orders are in place • Fabrication to complete in December 2004 • Bellows • Assembly and parts design complete • Need to draft assembly and part drawings

  10. Undulator Vacuum System • Vacuum System • System Layout • Short Break Section • Long Break Section • Vacuum Pressure within the System

  11. Vacuum System System Layout

  12. Vacuum System

  13. Vacuum System Short Break Section Schematic

  14. Vacuum System Drawn by SH Lee

  15. Vacuum System • Long Break Section Schematic

  16. Vacuum System Drawn by SH Lee

  17. Vacuum System Vacuum Pressure within the System (Thermal Desorption only) Red is at Tube Mid-Point Blue is Average Torr hours

  18. Vacuum System • Vacuum Pressure within the System (includes Thermal Desorption plus Photon Stimulated Desorption) Red is at Tube Mid-Point Blue is Average Torr hours

  19. Undulator Vacuum System/Mechanical • Beamline Diagnostics • RFBPM • Different type under consideration • Highlights of Schedule • Vacuum Testing of Diagnostics Components • What drives this issue • Status of Testing

  20. Beamline Diagnostics C-Band RFBPM now being considered instead of X-Band C-Band has the possibility of using industry supplied electronics According to published literature resolution ~30 nm

  21. Beamline Diagnostics • Highlights of the Schedule • Design work to start March 2005 • Timing of Design work based of funding during Continuing Resolution • Use intervening time to research C-Band RFBPM (ANL) • Goal is to have BPM mechanical design by June 2005 • Goal is to have (3) test BPMs by September 2005 • Currently this schedule is undergoing a review

  22. Beamline Diagnostics • Vacuum Testing of Diagnostics Components • What drives this issue • The Diagnostics Station is considering the use of motion components in the vacuum section where we do not have a lot of experience. • Slides and Stages • Motors • The initial concept was to put the motion components in the vacuum for reasons of positional accuracy. • The design is at a point where changes are possible to move things in and out of vacuum • The intention is to subject components to residual gas analysis and outgassing measurement to qualify them for use.

  23. Beamline Diagnostics

  24. Beamline Diagnostics • Status of Testing • A draft test procedure has been written that covers both residual gas analysis and outgassing measurement. • The Test Set-up is assembled • The Set-up has completed a troubleshoot/ clean-up process • The Set-up is in the process of establishing a base performance profile • Suppliers are being contacted for test samples

  25. Schedule • Diagnostics • Vacuum System

  26. Undulator Vacuum System / Chamber Design • Conclusions: • Prototype Chamber construction progressing • The prototype Bellows has been modeled and after issuing drawings it will enter the fabrication phase. • The order of the Beamline Components is still undergoing some adjustments but it is firming to allow design of the cradle assembly • A new direction for the RFBPM is being considered and work on it is schedule for March 2005 • Motion components vacuum testing has just entered the first stage of testing. • Questions
