Flying Wire Status

Flying Wire Status

• Main Injector
• Both Horizontal and Vertical Operational
• New design VRFT installed at MI-10 and appears to
  be fully functional. BUT have only 1 Spare!
• Recycler No Change
• Horizontal Operational
• Vertical has a binding feed-through. Problem is
  inside. Will replace it during summer shutdown.
• TEV
• Both E-11 and E-17 Horizontal sheared couplers
  and the magnetic feed through is binding. We
  replaced both couplers. I tuned the motion
  control system to make them fly stably. Both are
  returning profiles. Both should be repaired
  during the shutdown by rebuilding the
  feed-throughs.
• E-11 Vertical wire is also operating normally.

I tuned the motion control system to make them
fly stably at 5 m/s. Both are returning
profiles. Both should be repaired during the
shutdown by rebuilding the magnetic feed-through.
Vertical is still operating normally at 6 m/s.

IPM Status

• Main Injector
• Electrostatic Horizontal has very little gain.
  Difficult to see P-Bar signals on transfers.
• Electrostatic Vertical and Mark-II Operational
• Will work with Denton and Dave to understand
  current issues.
• Phil has offered up a first draft of a new design
  document. We plan to start discussions on it
  this week!
• Booster IPM will be discussed after the MI Plan
  to try to use as many of the same components as
  possible in both new designs.

• Tevatron
• Horizontal QIE crate was removed from the tunnel
  to troubleshoot a high error rate problem. We
  found a bad QIE board and replaced it.
• Ran the system for weeks. Used it to verify
  cables by injecting signals, and testing QIE
  board timing.
• Found and repaired some cable problems.
• Buffer Board firmware code was modified to report
  additional errors more accurately.
• Crate reinstalled in tunnel during last access.
• Some new errors are being reported that we are
  investigating. Need a short access.
• Added some scripts in the sequencer to turn off
  the IPM jacking mode for proton only stores to
  protect the MCP.
• That said, the IPMs are still taking data for
  every injection, up the ramp, during jacking, and
  during HEP. Good data is being logged!
