  1. Control System OverviewHamid ShoaeeControls System Manager • Injector control system commissioning & Support • Linac/BC2 Controls installation status • Plans for the remainder of e- Controls • Summary

  2. Accomplishments in the past six months • Providing ongoing support for the injector operation • New Software, as well as upgrades & enhancements • Commissioning of additional controls subsystems • Field installation of large amount of cable plant, networking, racks & electronics for BC2/Linac • Development of detailed plans for LTU, Undulator and E-Dump control system installation • Coordination of undulator control with ANL • Continuing the development of next generation applications software & feedback system

  3. Continuing support for the Injector Controls • Ernest Williams heading software engineering including EPICS system • “Software Day” concept proved very productive • Commissioning of new applications software such the bunch length measurement, MATLAB based feedback system • Enhancement and troubleshooting of released software • Commissioning of additional diagnostics

  4. The Toroid charge monitoring system was successfully commissioned

  5. Absolute charge measurement with Toroids • Mean ratio of Toroid to BPM charge = 1.45

  16. LLRF Work Completed since last review • All remaining stations in the injector and L1 were built, programmed and installed: • Transverse cavity in L0 • Phase cavity in L0 (alternative input source for laser phase feedback) • Phase cavity in L1 (diagnostic, no feedback) • Klystron phase & amplitude detectors (PAD) at 20-5, 20-6, 20-7, 20-8, 21-1 S-band and 21-2 X-band • Laser phase feedback enhancements

  19. Linac & BC2 Controls Installation • Detailed plans were in place Feb-March 2007 • The scope includes • Adding new magnets including pulsed horizontal dipole magnet • Adding BPM, x-collimator, OTR screen • Extending the new timing system • Safety systems (MPS, BCS) • BC2 installation, similar scope to BC1 • Very little engineering development • The biggest challenge has been meeting the schedule

  20. Linac & BC2 Controls Installation proceeding close to original schedule Controls Check out to start 11/7/07

  21. Cable plant installations are nearing completion

  22. Electronics Racks have been installed in the field

  23. BC2, Linac Controls checkout to start next week • All vacuum control equipment bench tested and loaded. • All network Switches, terminal servers, patch panels in place..

  24. Undulator Control • Close collaboration between SLAC and ANL • Separate weekly video conferences on Controls, BPM, BLM (Beam Loss Monitor) • Participation by SLAC personnel in planning, coordination and testing at ANL • Cavity BPM tests successful, meet sped • Undulator motion control FDR in 2 weeks • Have a design for BLM with schedule for development

  25. First beam tests of Undulator Cavity BPMat ANL (R. Lill) Cavity BPM undulator

  26. Controls for LTU, Undulator, E-dump BSY 550 m emittance diagnostic and collimation vertical bends dumpline horizontal bends undulator

  27. Controls for LTU, Undulator, E-dump • Identification of cable plant is nearing completion and documented in CAPTAR • We have developed electronics rack profiles for nearly all systems • We have an installation plan which is being integrated with the over all 2008 schedule • The challenge is coordination with other installations

  28. Developing detailed schedule for 2008 Controls installation

  29. Plans for the Next Six Months • Complete the BC2 installation and support the commissioning effort • Develop detailed plans for LTU, Undulator installation • Make major progress on the next generation high level applications software

  30. Conclusions • We have been providing ongoing support for the injector controls • The commissioning experience and the collaboration with physicists have been very effective in refining the systems • BC2/Linac Controls installation is proceeding well and close to the original schedule • We are developing detailed controls installation plans for the remainder of the e- regions • With the exception of a few systems, we are over the engineering curve, and the remaining challenge is maintaining the schedule
