Operational HighlightsOperational Highlights
• NuMI Great until 2nd horn problem knocked them off the
air
• MiniBooNE/SciBooNE Will ~hit design goal for the fiscal year in spite of
three month down time!

• Good running plus delayed shutdown => both beamlines ~hit their design goals for the fiscal year in spite of mistakes, unforeseen problems, etc.
No sense letting all the NuMI protons just sit there

Significant Activity Since Last PMGSignificant Activity Since Last PMG
• (1.1) Linac (1.2.2) Quad Power Supply Upgrade
• Continues adiabatically
(1.2.4) Linac LLRF Upgrade• Prototype FPGA board working and being used for tests• Unlikely to finish job during shutdown
– Goal: Complete at least station 5 and all prep work (VXI crates, etc) for other stations.
– Adiabatically upgrade remaining stations as hardware appears.
• (1.2) Booster Magnets, magnets, magnets
