  8. Diagnostics/Vacuum Overview

  9. Diagnostics/Vacuum Overview

  10. Diagnostic Devices • RF BPM • Cherenkov Detector • Charge Monitor • Radiation (µ-ray) Detector • Wire Scanner & OTR

  11. Diagnostic Devices – RF BPM • RF BPM to be developed using the Physics design from SLAC with the fabrication of the devices occurring at APS. • Prototype devices are to be made and then tested on the FFTB at SLAC

  12. Diagnostic Devices - Cherenkov Detector • For measuring Cherenkov radiation in-between each Undulator [33 total]. • Part of the machine protection system

  13. Diagnostic Devices - Charge Monitor • Single unit placed in Exit Section

  14. Diagnostic Devices - Radiation (µ-ray) Detector • The Radiation Detector is an array of scintillators that will be used to detect gamma rays that are produced from an unintended beam strike. • This devices is part of the machine protection system.

  15. Diagnostic Devices - Wire Scanner & OTR • Wire Scanner and OTR are contained within the Electron Beam and X-Ray Profile Diagnostics [EBXPD] Station • The intent is to make a station that has several platforms within it and that they can be selected remotely. • The current concept now it will have three positions: Wire Scanner, OTR, and Beam Pass-Through. This concept is expandable for future diagnostics devices. • The Beam Pass-Through will have a smooth bore tube for standard FEL operations.

  16. Vacuum System - Overview • Vacuum System Components • Vacuum Diagnostic Region • Flange Type Selection

  17. Vacuum System – Components • Undulator Vacuum Chamber - Concept

  18. Vacuum System – Components • Bellows - Concept

  19. Vacuum System - Vacuum Diagnostic Region • Used to determine problems in vacuum systems • Can be used for Leak Checking, analyzing gaseous contamination, and pumping. • One unit placed in start of the Entrance Section • One unit at end of Exit Section

  20. Vacuum System - Flange Type Selection • Recommendations:1. Short and Long Breaks: EVAC for tight insertion length and CF for others • 2. Entrance and Exit Sections: CF for most applications

  21. Major Efforts in Vacuum Schedule

  22. Vacuum System Costing

  23. Major Efforts in Diagnostics Schedule

  24. Diagnostics System Costing

  25. Milestones in Vacuum Schedule

  26. Milestones in Diagnostics Schedule

  27. Effort in Diagnostics & Vacuum by Year

  28. Conclusions • The loaded schedule has been a major focus for the last six months • While most of the items in the schedule are settled, there are a number of things that need further to work before a development plan can be made [EOU]. • Have started to work on conceptual ideas of key components. • Will be starting prototype work on the undulator vacuum chamber, bellows, wire scanner, OTR, and the radiation detection monitor. • Have plans to work with both APS and Nuclear Engineering to provide the needed additional personnel.
