  • 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

Linac bc2 controls installation
Linac & BC2 Controls Installation the same pulse

  • 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

BC2, Linac Controls checkout to start next week original schedule

  • All vacuum control equipment bench tested and loaded.

  • All network Switches, terminal servers, patch panels in place..


Undulator control
Undulator Control original schedule

  • 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

  • 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



Plans for the next six months
Plans for the Next Six Months original schedule

  • 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


Conclusions
Conclusions original schedule

  • 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
